Switched our password resets to PostedApi on a Friday afternoon. Took longer to brew the coffee.

Delivery speed is silly fast. Our invite emails land before the user has finished blinking.

The docs are so good our junior dev integrated the whole thing without asking me a single question. Slightly offended.

Support answered in 4 minutes, on a Sunday. With an actual solution, not a macro.

Bounce handling webhooks saved us from building an entire subsystem. Deleted a week of backlog just like that.

We moved 2M emails a month over in an afternoon. Zero drama, better inbox placement.

I have stopped thinking about email entirely. It just works. Best subscription we pay for.

Migrated from a big-name provider after our receipts kept landing in spam. Problem gone on day one.

Deliverability

Stellar inbox placement, no dedicated IP required

We review every new sender, enforce authentication best practices, and keep spammers off the platform entirely. The result: mail providers trust our IPs, so your mail sails straight to the inbox.

  • Carefully vetted shared IPs with spotless reputations
  • DKIM, SPF and DMARC handled for you
  • Genuine, human approval of every new account
How we protect deliverability
Transactional and broadcast email kept separate
Message Streams

Transactional and bulk email never mix

Password resets and receipts travel on infrastructure kept separate from newsletters and campaigns. A busy promo campaign can never drag your critical receipts into spam, and urgent mail always goes first.

  • Separate IPs, domains and suppression lists per stream
  • Broadcast streams for newsletters and announcements
  • Per-stream stats, webhooks and retention settings

Support

Getting started

From sign-up to sent in three steps

  1. Create your account

    Sign up and get 100 emails a month for $1.90. Verify a sending domain with a couple of DNS records.

  2. Grab your server token

    Every environment gets its own token and sandbox mode, so you can test safely before going live.

  3. Send your first email

    One API call or three SMTP settings later, your first message is on its way — usually in under a second.

“We stopped checking the spam folder years ago. PostedApi is the one vendor we never have to think about — it simply delivers, every single time.”
Elena Marsh Head of Platform, Northwind
