Deliverability02
Three records, three promises
SPF lists the servers allowed to send for your domain. DKIM adds a cryptographic signature proving the message was not altered. DMARC tells receivers what to do when either check fails — and sends you reports about it.
Getting them right
Keep a single SPF record per domain and stay under the ten-lookup limit. Use 2048-bit DKIM keys where your provider allows. Start DMARC at p=none to collect reports, then move to quarantine once you are confident every legitimate source is aligned.
CloudJet checks all three when you connect a mailbox and flags anything missing or misaligned before you send a single email.
Key takeaway
Deliverability is a habit, not a setting. Automate the guardrails, watch the signals, and scale only as fast as your reputation allows.
