1. Why limit email inboxes per domain?
To prevent domain fatigue and maintain credibility. Fewer inboxes reduce risk of blacklisting from high-volume sending.
2. What’s the ideal age of a domain before sending?
Minimum 3 weeks, ideally 3 months. Aged domains have better trust with mailbox providers.
3. Should I use HTML or images in my cold emails?
No. Plain text emails are less likely to be flagged. Avoid HTML, images, and links in early outreach.
4. What is Spintax, and why is it important?
Spintax creates dynamic versions of the same message to avoid triggering filters due to repetition.
5. How do I stay compliant with Google and Yahoo’s 2024 sender policies?
Authenticate all emails (SPF, DKIM, DMARC), include unsubscribe links, stay under spam thresholds, and avoid unverified leads.
