hi, I set up a self-hosted blog with ghost on digital ocean. everything works fine but emails going to spam. I have set it to ghost.silviogulizia.com and my domain is managed by cloudflare. my domain uses a gmail for business, and I set mx for this in cloudflare. my emails (subscription confirmation request) are going to spam because of dkim missing in headers. I duplicated the mx and added them for ghost.silviogulizia.com.
now, reading the documentation seems I have to use mailgun or amazon ses, but since I am getting email I assume I can use gmail too.
what I have to set to avoid spam?
