SPF, DKIM and DMARC Setup for Cold Email

How to publish SPF, DKIM and DMARC on a cold email sending domain, why alignment fails even when all three records exist, and what to check before sending.

How to choose

Quick Answer

Outbound tooling splits into four jobs, and most teams need more than one. A sending platform runs the sequences, a warm-up tool builds sender reputation on new domains, a verification tool removes bad addresses before they bounce, and a LinkedIn automation tool adds a second channel. Buying one tool that claims to do all four usually means accepting a weak spot in at least one of them.

What to Compare

  • Pricing model. Per-seat, per-inbox, per-LinkedIn-account and per-contacted-prospect pricing scale very differently once a team grows. Model your real volume before comparing headline prices.
  • Deliverability controls. Sending from your own mailboxes, throttling, inbox rotation and automatic pausing on bounce spikes matter more than raw send limits.
  • Channel coverage. Decide whether you need email only, or email plus LinkedIn steps inside the same sequence.
  • Data hygiene. Verification before sending protects the domain; check whether it is built in or a separate purchase.
