Cloudflare + AOP - Wordpress Emails

Hi all

Yesterday we enabled AOP on a Woocommerce/Wordpress site.

Overall performance immediately picked up, however this morning we came in to find that none of the emails had been sent from Wordpress via SendGrid.

We currently have all mail going through a CNAME and this is not proxied through Cloudflare.

Any ideas?

Does the CNAME point to a hostname that’s Proxied?

Mail hostnames should be an unproxied “A” record, not a CNAME.

CNAME points to SendGrid (Unproxied)
A points to a proxied domain via Cloudflare

If you’re using Sendgrid, I suggest you use the WPForms SMTP plugin so you connect directly to your Sendgrid API.
