Cold outreach lives or dies on per-mailbox limits, domain rotation, and reply-rate signals.
What phishing protection is#
Phishing is the use of deceptive email to steal credentials, money, or data. Defense combines domain authentication, inbound filtering, user training, and rapid reporting.
Why it matters#
Phishing remains the leading initial access vector in breaches. Domain owners also bear brand damage when their name is spoofed.
Implementation plan for B2B sales teams#
- Enforce DMARC p=reject so exact-domain spoofing fails.
- Register lookalike domains or monitor them for registration.
- Enable link rewriting and attachment sandboxing at the gateway.
- Run quarterly simulations and make reporting a one-click action.
- Apply BIMI so users learn what authentic mail looks like.
Priorities specific to B2B sales teams#
Cold outreach lives or dies on per-mailbox limits, domain rotation, and reply-rate signals. Weight your effort toward the steps above that address this constraint first, and measure with metrics that match how B2B sales teams generate value from email.
Common mistakes#
- Blaming users while leaving the domain unprotected.
- Allow-listing vendors broadly, which bypasses filtering.
Frequently asked questions#
Does DMARC stop all phishing?
It stops exact-domain spoofing. Lookalike domains and display-name spoofing require additional controls.
