Nice project! Can I offer a suggestion? Add support for goold old sendmail. Every email provider (Mailgun, Sendgrid, SES and others) have SMTP support and sendmail instructions. All of my home servers are already configured with it, so adding markdown to this setup would be sick.

Sure, I'm already planning to add other backends as an alternative to AWS. Feel free to add a note to issue #7 and I'll get on the case

Do you know whether the "62k free monthly emails limit" of the free-tier is available to existing AWS accounts, or a new AWS account must be created to enjoy free-tier billing?

Thanks!

EDIT: BTW, nice project!

Sounds like new and existing accounts, but only if the email originates within AWS EC2:

> When you call Amazon SES from an application hosted in Amazon EC2, you can send 62,000 messages per month at no charge. This Free Usage Tier benefit does not expire.

I believe its 62k free monthly emails for anyone, regardless of how long you've had your AWS account

Do you have to do your own queueing to make sure you're not sending too many emails all at once and they get marked as spam? Or does SES handle that for you? And if it doesn't, is there any service that will do this?

AWS handles that stuff for you. You can use SNS to monitor stuff like deliverability

Wow! That's amazing! What's the purpose of having your own dedicated IP then?
