Emailit

Every founder needs to send emails eventually, and this is yet another SMTP-to-REST wrapper promising to handle your transactional and marketing flows in one place. The feature list reads like every other email API on the planet — campaigns, templates, analytics — so nothing here is groundbreaking. That said, if they’re running a lifetime deal on AppSumo, the pricing math beats the per-email pricing of SendGrid or Postmark for anyone spinning up a new project, and sometimes “cheaper than the incumbents” is the only thesis a product needs.
