Greenvelope lets you send thank you cards online in seven steps: start a thank you note mailing from an artist-designed card, write a base note, add the people you are thanking, send yourself a test, personalize the notes that need their own words, send by email or by text message in supported countries, and check which notes Greenvelope recorded as opened. Nobody needs an account or an app to open the note, and you do not need a single mailing address or stamp.
After a wedding, a shower, or a party, keep a list of who you want to thank, what they gave or did, and one detail to mention. The steps below show how to turn that list into personalized Greenvelope cards, using the interface labels from Greenvelope's help center as read on November 12, 2026. For help with the words, use our thank you card wording guide; for other services, see our comparison of the best digital greeting card sites.
At a Glance
- Write thank you notes as gifts arrive. This guide's suggested targets are about two weeks after a shower and one to two weeks after a birthday; for wedding gifts, a commonly cited guideline is within three months of receiving the gift. A late note is still better than no note
- Keep a gift record from the first day: the giver's name, the gift, and one detail you can mention. Recording gifts as they arrive makes it easier to write each note accurately
- On Greenvelope, a thank you note is its own mailing. To thank the people from your invitation, import them from your address book and filter it to that invitation's mailing, then remove anyone who should not get a note
- Write one base note that is true for everyone, then use Customize / Send beside a name to give that person their own sentence about their gift
- Send by email or by text message in supported countries. Paid accounts start with 500 text messages, with more available to purchase
- Single mailings start at $19 for a guest list of up to 20 people, with pricing based on list size and no subscription required. Our cost guide covers larger lists
What to Have Ready Before You Send Thank You Cards Online
Before you open Greenvelope, gather the four things below. They decide how fast the rest goes.
- A gift record. One row per gift: who gave it, what it was, and a detail worth mentioning, such as where it lives now or what the money is going toward. A notes app or a spreadsheet both work. Start it as gifts arrive, not after.
- A way to reach each person. An email address or a mobile number is enough. If your invitation went out through Greenvelope, those contacts are already in your address book.
- A decision about who gets their own words. Anyone who gave a gift should read a sentence that could only be written to them. Guests you are thanking for coming can share one warm note.
- A target date. Pick the day you want the last note out, using the timing table below, and work backward in small batches.
How to Send Thank You Cards Online, Step by Step
Greenvelope's thank you notes are built in the Design step of a mailing and sent from its Send step, and the seven steps below follow that order. Each interface label is taken from the linked help center article.
1. Start a new mailing from a thank you note design
On Greenvelope, a thank you note is its own mailing, separate from the invitation that came before it. Click the New button in the left navigation to create a new mailing, then select your design. The thank you note collection is grouped by occasion, including wedding, bridal shower, baby shower, adult birthday, and graduation thank you notes.
Choose a design for your occasion, then check its available colorways and editable fonts on its product page before you start writing. Two examples show the range. Olive Branches by frau brandt sets the wording between two bands of watercolor olive branches on a white card. It comes in Green, and its product page lists a matching save the date and invitation. Little Lamb by Becky Nimoy Stationery puts a small lamb with a bow above the wording inside a scalloped gingham border, and comes in Orange, Blue, Green, Yellow, and Pink. Customization options vary by design.

A trial send to up to 10 people needs no credit card, so you can build the note and send it to yourself before you pay.
2. Write the base note
Greenvelope's card editor is under the Design step, in the Edit Card section, and the help center calls what you build there a "base" thank you note template. Click once in a text box to move or resize it and click again to edit the text. To add a photo from the day, click the Add Image or Video button.
The base note is what a person receives if you do not change anything for them. This sample base note is for guests who attended. For someone who sent a gift but could not come, replace the attendance lines when you personalize their card.
Thank you for celebrating with us.
Having you there meant so much to both of us,
and we're so grateful for your love and kindness.
With love, Priya and Daniel
For a shower or a birthday, swap the first line for the occasion and keep the rest short. You will add the sentence about each gift in step 5, so leave the base note general on purpose.
Two optional touches make a shared note feel addressed. Under the Design step, the Edit Envelope section has a Text tab where you choose what appears on the front of the envelope. And the help center's Top of Email Message article shows how to add a line above the card in the email: on the Preview step, click + Add a Custom Message. That message can use Insert Personalization to fill in each person's name, with fallback text for a contact who has no name on file.
3. Add the people you are thanking
Greenvelope keeps each mailing's list on its Send step, and a new thank you note mailing does not automatically reuse your invitation's guest list. Your address book, though, holds every contact you have added or imported for earlier mailings. To bring over the people from your invitation, click Add Contacts, choose Address Book, and use the dropdown in the popup to filter to a specific mailing. If you do not see Address Book, the help center notes that you may need to click More Options first.
Then read the list against your gift record. Remove anyone who should not get a note, and add anyone who sent a gift without being on the invitation list. Removing a contact from this mailing's list does not remove them from your address book. Every person listed counts toward the mailing's size, household members included, so trim the list before you buy.
If the event was not on Greenvelope, the same Add Contacts button takes an Excel or CSV file, a webmail account, a pasted list of email addresses, or a vCard file. To type people in, choose New Contact and pick an individual or a couple or family contact; the help center says to use couple or family only for people in the same household.
4. Send yourself a test and read it on your phone
Greenvelope adds the account holder to the list by default, so you can send a test card to yourself from the Send step before anyone else sees the note. Open it on your phone the way your aunt will, then check:
- Your names and the sign-off, letter by letter
- The photo, if you added one, and how the wording sits around it
- The front of the envelope and the line above the card in the email
- That the base note still reads well for someone who did not give a gift
- The list itself and the reply-to address, since people do write back to a thank you
- Any link you added to the card
If you sent tests to a few extra people during the trial, the help center notes that you can remove them afterward so they do not count toward the size you purchase.
5. Personalize the notes that need their own words
Greenvelope lets you edit the card for one contact at a time, and the help center says this card personalization is always on when sending thank you notes. On the Send step, click the Customize / Send button next to a contact. A window opens with your base note, where you can change the text and images for that contact alone, then choose to send the customized note now or save it for later. Send each customized note individually before you send or schedule the base note for the remaining contacts.
Work from your gift record, one contact at a time, and change only what needs changing: the greeting and a sentence or two about the gift. Check the greeting, the gift, and any reference to attending before you send. For someone who could not come, a natural replacement for the attendance line is "We missed you at the wedding and hope to see you soon." A customized version of the base note above might read:
Dear Aunt Leela and Uncle Raj,
Thank you for the espresso machine. We've used it every morning since we got home,
and Daniel now takes his latte art very seriously.
It meant so much to have you both there. We can't wait to see you in August.
With love, Priya and Daniel
Choose a small batch that fits your evening and work through the list a few notes at a time. Our wording guide has lines for money, group gifts, and the gift you will never use.
6. Send the base note to everyone else, now or on a schedule
Greenvelope sends the base note to any contacts you select together. On the Send step, select the Unsent filter, tick the checkboxes beside the people who should get the base note, and click the green send button at the top right to send to those contacts. A contact with no email address receives the card by text message in supported countries. If the contact has both an email address and a supported mobile number, you can choose text instead of email.
To pick a date and time instead, click Schedule Send. A scheduled send goes to every unsent contact, including anyone you add after scheduling, so send each personalized note individually before you schedule the base note. A scheduled note goes out on the date and time you set, which is how a note written on Sunday night can go out on Monday morning.
7. Check opens and fix anything undeliverable
Greenvelope shows what happened to each note on the same Send step. Click the Opened tab to see the people whose card Greenvelope recorded as opened, and the Undeliverable tab to see any address that bounced. For the reason behind a bounce, click the dropdown to the right of the contact and choose View Guest History. Correct the address, then send again to that contact.
A recorded open does not prove that someone read the note or that the message reached their inbox, and a note with no recorded open may still have been delivered. A thank you note asks nothing of the person who receives it: on Greenvelope, RSVPs belong to invitation mailings only. If you spot a typo in the base note after sending, you can go back and edit the card for up to five months, and the help center notes that an update changes the cards already sent. How that edit affects a note you customized for one contact is not described in the documentation reviewed, so proofread each personal note before you send it.
Sending Wedding Thank You Cards Online: An Illustrative Example
Greenvelope is where Priya and Daniel, a fictional couple, sent their wedding invitation to 84 people, so their contacts are already in their address book when the thank you notes come due. Their wedding is on Saturday, May 15, 2027, and they kept a gift record on a phone through the weekend.
- Monday, May 31, 2027. Home from their honeymoon, they open the invitation mailing's Track step and click the download icon at the bottom of the guest list to export the guest list and RSVPs. They add a gift column to that spreadsheet from their notes and the cards they saved.
- The same evening. They start a new mailing with Olive Branches by frau brandt, write a base note, and import the invitation's contacts from the address book: 84 people. They remove 6 people who could not come and did not send a gift, which leaves 78 people in 44 contact rows: 34 couples and 10 individuals. Then they send the note to themselves and read it on a phone.
- Tuesday, June 1, to Thursday, June 3. Each evening they open Customize / Send for 12 contacts who gave a gift, add a sentence about that gift, and send. That is 36 personal notes in three evenings.
- Friday, June 4. They select the 8 contacts still unsent, guests who came and have no gift on record, and send the base note, which thanks them for being there.
- Monday, June 7. The Undeliverable tab lists 2 addresses. They check View Guest History for each, text those two friends for a current email address, correct the contacts, and send again.
- Friday, June 11. One friend says the card never arrived. Using their paid account, Priya and Daniel copy that contact's personalized link from the Send step and send it to their friend another way. Copying personalized links is unavailable in Trial Mode.
The numbers reconcile: 84 people less 6 is 78; 34 couples and 10 individuals make 78 people in 44 rows; and 36 personal notes plus 8 base notes cover all 44 rows. All 44 original notes were sent by June 4, 20 days after the wedding. Delivery follow-up continued afterward. The dates and numbers are illustrative.
Email, Text, a Link, or Paper: How Each Thank You Note Travels
Greenvelope delivers a thank you note by email, by text message in supported countries, or through a link you share yourself, and one list can mix all three. Choose for each person by how they prefer to hear from you and which contact details you trust, not by their age.
| Route | Use it for | What to know |
|---|
| Email | People who prefer email | Recorded opens and undeliverable addresses are listed on the Send step's Opened and Undeliverable tabs |
|---|
| Text message | People you reach by phone, in supported countries | Put the mobile number in the contact's phone field. If the Send button does not appear for that contact, the help center says the number likely does not support text messaging through Greenvelope. A contact with both an email address and a supported mobile number can be sent the card by text instead of email |
|---|
| Personal link | Someone you already message on WhatsApp or another app | On the Send step, open the dropdown at the far right of the contact row and choose Copy Link / Send Plain Text. The link belongs to that contact, so send it only to them. Copying a link requires a paid account and is not available in Trial Mode. Greenvelope does not track WhatsApp delivery or read receipts |
|---|
| Paper | People who prefer a paper card | Greenvelope does not print, address, or mail cards. On a paid account you can download a high-quality version of the card to print yourself or take to a print shop |
|---|
Phones and carriers filter messages, and inboxes do too, so no route is certain to be seen. If someone tells you the note did not arrive, check their contact details and send it again. Our guide to text vs. email invitations goes deeper on choosing a channel for each person.
When to Send Thank You Cards After a Wedding, Shower, or Party
Greenvelope's Schedule Send can hold a finished note until the day you choose, but the best time to write is when the gift arrives, including gifts received before or after the event. The table gives this guide's suggested targets, not deadlines everyone follows. The wedding row follows Emily Post's guidance, read on November 12, 2026, which measures from the day you receive the gift.
| Occasion | Suggested target | Worth knowing |
|---|
| Wedding | Promptly after receiving the gift; a commonly cited guideline is within three months of receipt | The clock runs from when each gift arrives, so a gift sent before the wedding is due its note sooner than one that arrives afterward |
|---|
| Bridal or baby shower | About two weeks after the shower, as this guide's recommendation | Write the gift record as gifts are opened, while each guest and gift are still paired in your memory |
|---|
| Birthday party | One to two weeks after the party, as this guide's recommendation | For a child's party, a line from the child, typed by a parent, is plenty |
|---|
| Dinner or a weekend as a guest | Two to three days afterward, as this guide's recommendation | A short note to the host, sent while the evening is still fresh |
|---|
If you are past your target, send the note anyway and acknowledge the timing in one sentence. For the invitations that come before all this, see our timing guide.
Five Mistakes to Avoid When You Send Thank You Notes Online
Greenvelope handles the design and the delivery, but these five mistakes are about judgment, and each has a simple fix.
- One identical note to everyone who gave a gift. The base note is for guests you are thanking for coming. A gift deserves a sentence of its own, added with Customize / Send.
- Scheduling before the personal notes are out. A scheduled send covers every unsent contact. Send the personal notes first, or schedule only when the base note is right for everyone still unsent.
- Importing the invitation list without reading it. The address book brings over the contacts from that mailing. Check it against the gift record, remove the people who should not get a note, and add the neighbor who dropped off a gift.
- Naming the amount of a cash gift. Say what the money is going toward instead.
- Saving all of them for one sitting. Choose a small batch that fits your evening and work through the list a few notes at a time.
Frequently Asked Questions
How to send thank you cards online?
On Greenvelope, start a new mailing from a thank you note design, write a base note in the card editor, and add the people you are thanking on the Send step. Send yourself a test, use Customize / Send to give individual people their own words, then send the rest by email or by text message in supported countries. The Send step's Opened and Undeliverable tabs show which notes were recorded as opened and which addresses bounced.
Can I write a different message to each person when I send thank you cards online?
On Greenvelope, yes. Card personalization is always on for thank you notes, so the Customize / Send button beside a contact opens your base note for that one contact. You can change the text and images, then send it right away or save it for later. Send each customized note individually; contacts you select together receive the base note as written.
Can I send thank you cards to the same guest list as my invitation?
On Greenvelope, yes, by importing it. A thank you note is its own mailing with its own list, and your address book keeps the contacts from earlier mailings. On the Send step, click Add Contacts, choose Address Book, and filter to the invitation's mailing. Review the list before you send, since every person on it counts toward the mailing's size.
Can I send a thank you card by text message?
On Greenvelope, yes, in supported countries. Add the person's mobile number in the contact's phone field, and a contact with no email address is sent the card by text message when you send. If the contact also has an email address, you can choose text instead of email.
How long do you have to send thank you cards after a wedding?
Send each note promptly after you receive the gift. A commonly cited guideline is within three months of receiving it, so a gift that arrives before the wedding is due its note sooner. If you are past that point, send the note anyway with one sentence about the delay; a late thank you is better than none.
How much does it cost to send thank you cards online?
On Greenvelope, single mailings start at $19 for a guest list of up to 20 people, with pricing based on list size and no subscription required. A trial send to up to 10 people needs no credit card. Paid accounts start with 500 text messages, with more available to purchase.
Is it OK to send thank you cards by email instead of mailing them?
A Greenvelope thank you card can be a thoughtful choice for someone who welcomes digital cards. Write a personal message about their gift or kindness. Choose a handwritten note when you know that is what the person would appreciate.
