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.

Every new account gets a built-in sandbox — test your integration before you send a single real email.
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.
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.
Fast delivery is only half the job. When you need a hand, our team of email nerds replies fast — and premium support is never an upsell.
Customer feedback collected over the last 60 days.
A clean REST API with detailed error responses, batch sending and a sandbox mode for safe testing.
Legacy app? Point your SMTP settings at PostedApi and get modern deliverability in two minutes.
Responsive starter templates, a testable template syntax, and an editor your whole team can use.
Receive email at your domain and get it pushed to your app as tidy, parsed JSON.
Organize sending by product, client or purpose — each with isolated stats and settings.
Bounces, opens, clicks and delivery times per provider — the numbers that actually matter.
Sign up and get 100 emails a month for $1.90. Verify a sending domain with a couple of DNS records.
Every environment gets its own token and sandbox mode, so you can test safely before going live.
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.”
Join thousands of teams who stopped worrying about deliverability. Start at $1.90, scale when you're ready, cancel anytime.
