Comparing SES Wrappers:
Transmit vs. Sendy vs. Sidemail
Should you self-host PHP? Or use a managed wrapper? Here is the honest breakdown of the AWS SES ecosystem.
The SES Ecosystem has 3 tiers: Self-Hosted (Sendy), Lightweight Wrappers (Sidemail), and Infrastructure Suites (Transmit). Your choice depends on how much maintenance pain you can tolerate.
- Sendy: Cheapest ($69), but requires you to manage a PHP server, CRON jobs, and database upgrades.
- Sidemail: Great lightweight wrapper, but lacks advanced specialized features (Warmup, Inbound Parsing).
- Transmit: The 'Vercel for SES'. Fully managed, API-first, with per-customer reputation isolation and enterprise features like Inbound and Dedicated IPs.

Transmit

- The Hidden Cost of Self-Hosting
We love Sendy. It was the pioneer. But "One time fee" is comprehensive deception. You pay with your time.

Analysis: Sendy v5 uses "grouping" as a column name. This is a reserved word in MySQL 8. Your entire campaign is broken until you manually ALTER TABLE.
If you choose Sendy, you are essentially becoming a Linux Sysadmin. Do you have your upgrade script ready?
Do you want to be debugging STRICT_TRANS_TABLES SQL modes on a Friday night?
Or do you want to send email?
It is the synthesis.
Beyond the Wrapper
Choosing a control plane is step one. Step two is securing the connection and scaling your reputation. Transmit also ships an open-source MCP server, so AI agents in tools like Claude or Cursor can send emails, manage contacts, and check domain health without leaving your editor.
