Hey Jasper.
For the first part, I’ve found http://zoho.com/mail|zoho.com/mail to be really helpful to set up multiple aliases (with different domain names) for a single mailbox
Are you looking for a simple editor to compose email & send to multiple recipients or you’re trying to do it with your backend flows?

Thanks Goutham, I’ll have a look at Zoho! Ideally it would be like an API where I send some data (name, recipient, etc), fills those in in a pre-made template. I think the editor doesnt need to be connected to the email API of course. if i can upload an HTML template, I could make the email design somewhere else as well

I’m in a similar boat as you Jasper Schoormans, I’m still writing html and using templates to send emails using SMTP… not scalable! I have been told by people to try either SendGrid or Postmark, which I will try out in due course.

Yeah we should step up our game Sam SendGrid seems to be free for 100 emails a month! Worth a try

Shameless plug: I’m currently working on a product to send emails directly to SaaS customers http://mailboat.io|mailboat.io & trying to get feedback with the MVP launch in a week. Let me know if that’s useful for you guys Sam Cox Jasper Schoormans

Sure Goutham J I’ll take a look at it when you’re ready for MVP launch - the landing page looks good and conveys the info I need.
The first thing that jumps to mind is sender reputation (might not be the right name). Part of the benefit of paying for email delivery would be that you should be more likely to get to inbox instead of junk due to a good sender reputation; is that something you’ll be considering?

Mailgun and AWS work well for me for transactional emails. Google Workspace for mailboxes. Having your own mailserver is annoying because a lot of it is going to spam.

Sam Cox Absolutely Sam. Deliverability is the primary focus of this product as this was personally from a frustration of emails landing in promotions despite the email content following best practices. It turned out that existing email providers have a shared IP pool where one bad actor spoils deliverability for the others & you’d have to pay a lot separately for dedicated IP. With http://mailboat.io|mailboat.io, all of this is handled out of the box as it’s relying on AWS infra 😊
