I've spent a long time bouncing around ESP - mailchimp, mailerlight, mailigen, aweber etc. They are all so complicated - I just want to send emails and have the odd HTML form embedded or pop up, maybe even a landing page.

Sendfox does all of that and it is simple. Add 3 x CNAME to your domain and you have spf, dkim and dmarc all set up. Small test groups all inbox on Gmail and hotmail/outlook.

The backend is powered by sendgrid, branding is unobtrusive and you can remove it for $10 a month anyway.

Double option is available and can be toggled on/off.

Negatives? If you don't know how/want to stick your emails together from scratch then this may be an issue for you in sendfox. Compose is basic but I like it because it allows the freedom to design how you like (all those fancy images are just gonna put you in the promotions tab anyway. ) Same goes for forms and landing pages, they are real basic, but you could always spice them up a bit with the odd line of HTML to add color & images.

Seriously, this is a great deal. Just so long as they get their sender policies and policing right and don't let the free tier ruin the whole thing.

I only have a small list at the minute but I feel a stack coming on!
