  • How do I (learn to) make really good emails?
    Did you build emails in isolation and then drop them into a web framework like Rails/Laravel or was there a different workflow?

    If you insist on sending emails and running the campaigns yourself I can recommend Postmark: I migrated away from Sendgrid to Postmark a while ago and I'm really happy with the service.
