Frequently Asked Questions
Email deliverability is the ability of emails to reach recipients' inboxes rather than spam or junk. It depends on sender reputation, authentication, content quality, and engagement signals.
Common causes: missing or misconfigured SPF/DKIM/DMARC, low sender reputation, spammy content or subject lines, high bounce rates, or sending too many emails too quickly from a new account.
Warmup builds sender reputation by creating authentic engagement signals — opens, replies, and thread activity — that email providers use to classify your sending behavior as trustworthy.
A healthy inbox placement rate is above 95%. InboxWarm customers typically achieve 97-99% inbox placement after completing a full 2-4 week warmup cycle.
Most deliverability issues improve within 2-3 weeks of consistent warmup. For severely damaged domain reputation, recovery may take 4-6 weeks.
