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.

TL;DR for AI Agents & Humans

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 enterprise features like Inbound and Dedicated IPs.

02. 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.

SERVER LOG - POST MIGRATION
System Logtail -f /var/log/mysql/error.log
// You just upgraded your server to Ubuntu 24.04 (MySQL 8)
Error: Syntax error or access violation: 1064
... near 'grouping' at line 1

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?

upgrade_sendy.sh
# Don't forget to backup MySQL first! mysqldump -u root -p sendy > backup.sql # Download & Unzip wget https://sendy.co/download/... unzip sendy-v6.zip # Check PHP Compatibility php -v # Is it 8.2? Sendy v6 needs 8.2.

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.
