Email deliverability is the foundation of any outbound strategy. Without it, even the best-crafted message never reaches your prospect.
The Authentication Trifecta: SPF, DKIM, DMARC
These three DNS records tell receiving mail servers that your emails are legitimate. SPF defines which servers can send on your behalf. DKIM adds a cryptographic signature. DMARC ties them together with a policy for handling failures.
Warm-Up Strategy
New domains and mailboxes need a gradual ramp-up. Start with 10-20 emails per day to engaged contacts, increasing by 10-15% daily over 2-3 weeks. Monitor bounce rates and spam complaints throughout.
Send Pacing
Even after warm-up, respect daily limits. Most providers recommend staying under 200 cold emails per mailbox per day. Distribute sends throughout business hours and avoid sending patterns that look automated.
