Frequently asked questions
What's the realistic inbox-placement rate for B2B cold email in 2026?
For a well-warmed domain with strong reputation: 85 to 95 percent inbox. For a new or recently-burned domain: 30 to 60 percent. The gap is enormous and improves with discipline.
What's the biggest deliverability mistake B2B teams make?
Sending too much volume from a single primary domain. The fix is multiple subdomains for outbound (different from the corporate domain) plus warmup automation. Sending 1,000 cold emails per day from your main domain is how you lose your own inbox.
How does AI affect email deliverability?
Spam classifiers got smarter at detecting templated AI-written emails. Generic AI output detects at high rates. Human-edited AI drafts perform fine; fully-automated AI sequences degrade deliverability fast.
What's email warmup and is it necessary?
Warmup gradually increases sending volume on a new domain while simulating engagement signals. For domains that have never sent outbound, it is necessary. Skipping warmup puts you in the spam folder before you have sent your first real email.
How does Landbase relate to deliverability?
Landbase does not run the SMTP. That is your sequencer's job. Landbase improves deliverability indirectly by ensuring you send relevant emails to verified addresses, which is what spam classifiers actually measure.
