Warmup builds reputation — but authentication, blacklists, and content decide whether your mail ever reaches the inbox. We watch all of it.
Misconfigured auth is the single biggest reason legitimate mail lands in spam. The platform monitors all three with a guided fix wizard.
Sender Policy Framework lists which servers may send mail for your domain. A missing or over-broad SPF record gets your mail flagged. We verify it resolves, stays under the 10-lookup limit, and authorizes the right senders.
DomainKeys Identified Mail cryptographically signs your messages so receivers can confirm they weren't tampered with. We check your selector publishes a valid public key and that outgoing mail is actually signed.
DMARC tells receivers what to do when SPF/DKIM fail, and gives you reporting. We monitor your policy (none / quarantine / reject), alignment, and parse the aggregate reports so you can tighten enforcement safely.
Continuous checks across major RBLs. Get alerted the moment your domain or sending IP gets listed — and how to request delisting.
Score message content against common spam triggers (link ratios, risky phrases, image-to-text balance) before you send.
