As wedding planners, one of the most common questions we get from couples is: “How do we actually mail our invitations?” It sounds simple… until you’re staring at a stack of beautiful stationery and suddenly questioning everything. Like most things in wedding planning, it’s not difficult, but the details matter.

We’ve gathered our tried-and-true tips (paired with current USPS guidance) to walk you through the process so your invitations arrive safely, beautifully, and exactly as intended.

Step One: Stamp Your RSVPs!

To make it easy for guests to respond, always pre-stamp your RSVP envelopes. This is one of those small details that makes a big impact.

RSVP with envelope: A standard Forever stamp is typically sufficient (as long as the card is standard size and weight).

Postcard RSVP: Use a postcard stamp, which is lower in cost than a standard letter stamp. Be sure to bring one of your postcards to the post office when buying the stamps to ensure the postcard dimensions fit within postcard standards.

Tip: Forever stamps remain valid regardless of postage increases, which we love. However, if your RSVP card is oversized, unusually shaped, or heavier than standard cardstock, confirm the correct postage with your local post office before mailing.

Also don’t forget:

  • Return address on the RSVP envelope

  • Correct spelling of your return address

  • Clear response deadline printed on the card

Do NOT stamp RSVP envelopes for international guests. Local international postage from that country is required to mail back to the United States.

Step Two: Double-Check Your Addresses

Whether your stationer, calligrapher, or online printing service addressed your envelopes, always cross-check them against your final guest list. Yes, even if they’re a professional.

Even with the best vendors, mistakes happen:

  • Missing guest envelopes

  • Misspelled names

  • Missing apartment numbers

  • Incorrect ZIP codes

  • Outdated addresses

Digital address collection tools are incredibly helpful, but they are not foolproof. Taking a few extra minutes to review everything now will save you from returned invitations later. If there are corrections, you can either hand-address the correction with a blank envelope or reach out to your stationer to see if they can, and are willing, to reprint. Unless the error is the responsibility of the stationer, there likely will be a fee.

Extra diligence before going to print goes a long way!

Step Three: Properly Stuff Your Invitations

There is absolutely a method to this, and yes, we care about it!

With the envelope lying down on the front, guest-addressed side, place the main invitation inside the envelope, front side facing you and rotated to the left (if portrait layout).

Tuck the RSVP card under the flap of the RSVP envelope (printed side of the RSVP card facing up and the flap extending from the left side of the card).

Layer additional inserts (details card, map, accommodations, etc.) from largest, on the bottom, to smallest, on top. It’s likely that the RSVP card/envelope are on top.

Insert the entire stack into the mailing envelope, printed side up, on top of the invitation. Rotate to the left, if need be, to match the invitation.

When your guest opens the envelope from the backside, everything should be facing up.

Pro tip: If you're including:

  • Wax seals

  • Ribbon

  • Vellum wraps

  • Belly bands

These elevate your design,but they can also increase postage and may require hand-canceling. Not only does the assembled invitation need to adhere to weight restrictions, but also be within a certain thickness to avoid being considered a “package”, so be sure to check with the post office before dropping your invitations in the mail.

Step Four: Seal Your Envelopes Securely

You can absolutely keep it old-school and seal envelopes by moistening the adhesive and pressing firmly, but don’t rush this step.

To ensure a secure seal:

  • Press firmly along the flap

  • Run your fingers across the seal to fully adhere

  • Stack flap-side down under a heavy book for 10–15 minutes while drying

If using:

  • A damp sponge or cloth: avoid over-wetting

  • Wax seals: allow full drying time before stacking

  • Envelope glue pens: test first to prevent warping

Modern envelopes don’t always have the strongest adhesive, so take a little extra care here. Permanent, double-sided tape or adhesive tape runners work well, and are our standard go-to methods for sealing envelopes.

Step Five: Weigh a Fully Assembled Invitation

This step is critical.

Bring one fully assembled invitation (including all inserts and embellishments) to the post office to determine exact postage.

Why?

  • Heavier cardstock increases weight

  • Square envelopes require additional postage

  • Larger envelopes can require additional postage

  • Thick embellishments may make your suite “non-machinable”

  • Rigid envelopes can incur extra fees

The USPS offers a wide range of wedding-themed stamp designs, and you can also curate vintage stamps for a more custom look, just be sure the total value meets or exceeds the required postage. We also suggest coordinating the RSVP envelope stamp with the mailing envelope postage.

Note: International postage will be different depending on destination and should always be confirmed at the post office.

Step Six: Mail Them the Smart Way

Rather than dropping your invitations into a mailbox, take them directly to the post office counter.

You can:

  • Request hand-canceling (a manual ink stamp instead of machine processing)

  • Ask about non-machinable handling if your invitations are delicate

  • Confirm postage one last time

We highly suggest dropping them off in the morning to allow time for the postal worker to hand-cancel before the end of the day. Please also note that even if your invitations are hand-canceled, there is no absolute guarantee they won’t go through automated processing later. However, this step significantly reduces the risk of damage, and we always recommend it.

Bonus: Timing Tips

  • Mail invitations 10 - 12 weeks before the wedding.

  • For destination weddings, mail 3 - 4 months in advance.

  • Send save-the-dates 8 - 12 months ahead.

And always order 10 - 15 extra invitations for:

  • Keepsakes

  • Last-minute additions

  • Photography flat lays

  • Address mistakes
