I've tried this. Most of my emails land in either "Promotions" or "Updates", or worse – Spam.
If you really want your emails to be delivered to most recipients Inbox – I would not recommend this.
To validate – please go to https://www.mail-tester.com https://www.mail-tester.com – in 15 seconds it will evaluate and print your email score (you send it a dummy email). The main thing I see with using free gmail as a custom domain proxy SMTP is: It does not do DKIM (email signatures) except for @gmail.com or google workspace accounts. This reduces the sender score by a LOT.
Edit: The same is also true with forwardemail.net or any "incoming" email routing (free or paid). Because incoming email is just one step of using a custom domain. The main thing is the "Outgoing" email server. Unless outgoing email has full DKIM support for your custom domain, your emails are going to struggle reaching the recipient.
- jaygooby 4y agoPost author here - I sent an email to mail-tester.com from an email alias I've set up as described in my post; it's gets a "Good stuff. Your email is almost perfect" and a score of 7.5/10 -0.5 from SpamAssassin (FREEMAIL_FORGED_FROMDOMAIN & HEADER_FROM_DIFFERENT_DOMAINS) -1 for not being DKIM signed -1 Because Google is in some blacklists The critical steps, which I think people often gloss over are the SPF (https://jay.gooby.org/2022/05/06/use-a-basic-gmail-account-to-send-mail-as-with-a-domain-that-uses-cloudflare-email-routing#11-edit-your-spf-record https://jay.gooby.org/2022/05/06/use-a-basic-gmail-account-t...) and DKIM ones (https://jay.gooby.org/2022/05/06/use-a-basic-gmail-account-to-send-mail-as-with-a-domain-that-uses-cloudflare-email-routing#12-edit-your-dmarc-record https://jay.gooby.org/2022/05/06/use-a-basic-gmail-account-t...) without these, you'll definitely have deliverability issues.
