Verification codes, password resets, order confirmations — the emails your users can't miss. One API call and it's delivered.
We built the transactional email service we always wanted — fast, reliable, and with none of the complexity.
Built on Amazon SES — one of the most trusted sending infrastructures in the world. Your emails land in inboxes, not spam folders.
A clean, RESTful API that takes minutes to integrate — not days. Send your first email with a single POST request and a few lines of code.
Track every email from send to delivery. See opens (with country), bounces, and failures as they happen — and resend any email in one click.
Authentication is handled from day one — and monitored continuously. We alert you if a record goes missing and block sends until it's fixed.
Go beyond transactional. Send newsletters and bulk campaigns to mailing lists — with blocklist management, open tracking, and per-campaign stats. Premium feature.
No monthly minimums. No overages. No gotchas. Per-email pricing that scales with you — from 100 emails to 100 million.
See how sendvia compares to traditional transactional email services.
sendvia runs on your own Amazon SES account — the cheapest sending infrastructure in the industry — with a simple $19/mo flat fee on top. No inflated per-email margins.
