Attentive authentication
Attentive runs SMS-first retention programs with a growing email channel. 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 | CNAME records generated by Attentive | 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 Attentive 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 Attentive senders hit a few specific problems.
Email is added on top of an existing SMS program, so the sending domain is usually brand new.
Subscriber growth is fast, and fresh addresses have no engagement history.
Promotional cadence is high by design, which needs a strong reputation to sustain.
Passing SPF, DKIM and DMARC confirms authentication, but it does not reveal where your campaigns actually land. Warmy helps Attentive senders test inbox placement across major providers, monitor domain reputation, identify blocklist issues and detect authentication problems before a campaign is sent.
