Two services for email routing.
Cloudflare Email Routing
If you don't use cloudflare, you can use https://forwardemail.com instead.
Note that their free plan requires you to put all the emails into a txt dns entry.
Sending
Setting up send from
You can send from your gmail by doing the following:
- Update your TXT dns record to
v=spf1 include:_spf.mx.cloudflare.net include:_spf.google.com ~all
- Follow https://gist.github.com/irazasyed/a5ca450f1b1b8a01e092b74866e9b2f1
This drawback is that this requies an app password on your Google account and the email does not pass DKIM.
Sendgrid
Sendgrid's free plan allows 100 emails per day.
This allows DKIM with domain verification
Some of their IPs are on spam lists.
Purelymail
Purelymail is a $10 per year email service.
