How to Add a Return Envelope When Creating a Job

USPS mail envelope example with double windows

Look, not every mail-related question is a high-stakes compliance issue. Sometimes it’s just: “Hey… how do I add a return envelope to this thing?”

And, we get it. If you haven’t done it before, this stuff can feel weirdly tricky. But here’s the good news: it’s incredibly easy—and we made a video to walk you through it, just in case clicking buttons under pressure isn’t your thing.

So, if you’re sending out statements, invoices, ballots, or anything else where you actually want a response (like, in the mail, with a stamp and everything), you’ll want to include a return envelope.

Let’s break it down.

What’s a Return Envelope and Why Does It Matter?

A return envelope is exactly what it sounds like: a second envelope, tucked inside your mailing, that your recipient can use to mail something back to you.

  • They open your letter
  • They see the return envelope
  • They use it
  • Everyone wins

This is especially common for:

  • Payments (yep, checks are still a thing)
  • Forms and ballots
  • Surveys and reply cards

If you don’t include one, your return rate drops. People are busy, and no one wants to hunt down an envelope like it’s 1997, you know? In fact, you can’t find just one and no one wants to buy a whole pack of envelopes either. So, best case scenario is to include one yourself for your customers.

How to Add a Return Envelope to Your Mailing

Ready? It’s literally one step. (Told you it was easy.)

When setting up your job online, when you get to the inserts page, simply click on the blue “Add An Envelope” button and select with #9 you want to choose.

Boom. Done.

The return envelope will be inserted automatically along with your letter or statement. No extra work. No extra clicks. It’s already built into the workflow.

Still unsure? Don’t forget we made a YouTube video that shows you how to add a #9 return envelope.
Because sometimes it’s just easier to see it than read about it.

A Few Bonus Tips

  • Want it pre-addressed? No problem.
  • Need a windowed return envelope? That’s an option.
  • Need a #8 ballot or even a 6 3/4 return envelope? Both are options too.

We’ve thought through the logistics so you don’t have to.

Make It Easy for Them to Respond

If you want a reply, make replying easy. It’s that simple.

Adding a return envelope removes friction, increases response rates, and gives your mail that “oh wow, they actually thought this through” energy.

We’re not saying it’ll make your recipients love you more—but… actually, yeah, it might.
