The work

Three surfaces. Then it sends.

Your layout

Upload the PDF you already designed. Names and dates go where you marked them.

The whole list

One CSV. One queue. SES takes the batch so you are not exporting by hand.

A page they can open

The code on the certificate is the same one on the public record. Revoke, and it says so.

Who it’s for

Same product. Different lists.

A chapter weekend, a six-week course, or a two-day summit. The sheet changes. The send does not.

2,400

Hackathons

Winners, participants, and volunteers from one sheet. Sent before the closing stage is over.

860

Courses

A completion certificate for every person who finished, with a page their employer can open.

1,120

Talks & summits

Speaker, mentor, and attendee files without a separate export for each role.

How a batch goes out

Four moves, then it sends.

01

The list

Drop the roster. We read names, emails, and the award line.

The fields

Column in the file, place on the PDF. That is the whole mapping.

03

The letter

A short note, the PDF, and the code that opens the public page.

Aria, the certificate is attached.

SES sends the batch. A hard bounce puts that credit back.

The file, the map, the names that went out.

The roster is ready

The public page

A code on the paper. A record on the web.

Anyone with the identifier can open the same page. Revoke one name and that page is the thing that changes — you do not resend the batch.

  • Name, event, and award as issued
  • Date on record
  • Revoked state, if you turned it off
  • A LinkedIn link for the recipient

Questions

Before you upload the sheet.

Credits, your PDF, a bounce, and sending from your domain.

01

Do the 25 free credits expire?

No. Free credits and paid packs stay on the account until you send them.

02

Can I use the certificate PDF we already designed?

Yes. Upload it, mark the name and date, and each row fills one copy.

03

What happens if an email bounces?

A hard bounce returns that credit. You are not charged for a mailbox that never existed.

04

Can we send from our own domain?

Yes, on paid plans. Connect the domain, add the DNS records, and SES sends as you.

05

How does LinkedIn fit in?

The public page has a link the recipient can use. You do not paste certificates in by hand.
