Different industries, same plot: move to PostedApi, watch the metrics behave.
Northwind runs a marketplace where every order, offer and payout notice travels by email. After migrating, their transactional mail stopped sharing reputation with promotional blasts — and inbox placement recovered within weeks.
Heliotrope Health sends appointment reminders and lab notifications for hundreds of clinics. They needed strict data handling, a full content history and delivery they could stake a patient's visit on — not marketing promises.
Brightstack's B2B platform notifies thousands of business customers, each with its own templates and sending rules. Message Streams keep every tenant's mail isolated, so one noisy customer can't dent anyone else's deliverability.
Unsolicited, unedited, occasionally unhinged. We collect them anyway.
Migrated our receipts on a Tuesday before lunch. By Friday we'd forgotten which provider we used before. That's the whole review.
Our renewal notices used to land in spam so consistently users thought we'd gone out of business. PostedApi fixed that in a week.
Support replied with the actual answer, including the curl command I needed. I printed the email and put it on the fridge.
We send password resets for a product with 4M users. The scariest part of switching providers took eleven minutes.
The bounce webhook told us a customer had a typo in their own domain before their customers did. Genuinely impressed.
I've evaluated four email providers and PostedApi is the only one whose pricing page didn't make me feel like I needed a lawyer.
“PostedApi is the one vendor whose monthly invoice is the most boring email we receive. Everything else — the delivery, the stats, the support — simply works, and then gets out of the way.”
