- Sender reputation — cold email glossary
A mailbox provider's ongoing assessment of a sending domain, built from bounce rate, spam complaints, and engagement over time. Low reputation means spam-folding by default, regardless of content.
- SPF — cold email glossary
Sender Policy Framework — a DNS TXT record listing which servers are authorized to send mail for your domain. Mail from an unlisted server looks forged, whether it actually is or not.
- Cold email & deliverability glossary
Plain-language definitions for the terms that come up in cold outreach and email deliverability: bounce rate, catch-all, SPF/DKIM/DMARC, sender reputation, and more.
- Bounce rate — cold email glossary
The share of sent emails a mail server refuses to deliver. A hard bounce means the mailbox does not exist; a soft bounce means it is temporarily unreachable.
