You do not have to learn SPF, DKIM and DMARC to have them done properly. We publish the records, prove they work, and can keep managing them afterwards.
A real engineer replies within one business day. The first look is free, with no obligation.
Matano IT publishes the records, verifies with live send tests, and hands back a green report card. Bigger jobs are scoped as Matano IT consulting.
Records drift. Staff join and leave, a new newsletter tool gets added, a provider changes its sending IPs, and the setup that passed in March quietly fails in September. Matano IT can take on ongoing email administration and management: mailbox and account changes, authentication kept current as your senders change, blocklist trouble handled on your behalf, and someone to call when a message does not arrive. Scoped to your setup and quoted before anything starts.
