Nothing you built needs changing — the changelog has the details.
{{ first_name | fallback: "friend" }}ESPs earned their (growing) price when deliverability was a dark art and automations were bolted on because there wasn't a better way. Not anymore.
Mimeo puts it all in your hands. Intuitive automations you own. Sending you control. A bill that never counts your subscribers.

It also helps you email responsibly by auto-monitoring complaints and stopping sends before you damage your domain reputation and standing with senders like Postmark and Amazon SES.

Before photocopiers, printing lived at the print shop — professional equipment, professional prices, a toll on every copy.
Then the mimeograph put the whole apparatus on a desk. Ink the drum, turn the crank: as many copies as you need. Owning the machine made everyone a publisher.
Email marketing rebuilt the print shop — your audience and your automations, rented back to you at a price that grows with your list.
