Maropost authentication
Maropost runs high-volume marketing and commerce messaging. Gmail, Yahoo and Microsoft require authenticated email from bulk senders, so a authenticated sending domain with valid SPF, DKIM and DMARC is the baseline for reaching the inbox.
| Protocol | Purpose | Typical record | What it verifies |
|---|---|---|---|
| SPF | Authorizes sending infrastructure | TXT record on the sending domain | The sending server |
| DKIM | Adds a cryptographic signature | DKIM records generated by Maropost | The message and the signing domain |
| DMARC | Defines alignment and failure policy | TXT record at _dmarc | The visible From domain |
Record names and values differ per account. Always copy them from your own Maropost screen rather than from a generic example.
Why placement drops
Authentication only proves who sent the message. Placement depends on reputation, engagement and list quality - and Maropost senders hit a few specific problems.
High-volume publishers hit spam traps faster than any other sender type.
Multiple brands and domains run in parallel under one account.
Aggressive acquisition sources introduce risky addresses.
Passing SPF, DKIM and DMARC confirms authentication, but it does not reveal where your campaigns actually land. Warmy helps Maropost senders test inbox placement across major providers, monitor domain reputation, identify blocklist issues and detect authentication problems before a campaign is sent.
