What Makes Us #1?
From inbox warmup to spam checks, emailwarmup.com gives you everything you need to send better emails and get more responses.
Real Inboxes, Real Warmup
EmailWarmup.com runs on real inboxes across Gmail, Outlook, and other major providers, using personal and business accounts so your warmup is effective whether you’re B2B or B2C. Behind it is a live network of 20,000+ active emails, so you get to the highest inbox rate in the shortest period of time.
Natural Engagement
We send realistic emails to real inboxes, automatically opening your warmup emails, replying to them, marking them as important, and moving spam or junk back to the inbox. Our email warmup creates threaded conversations that look natural — read emulation includes realistic scrolling and time spent on each email and clicking CTAs in warmup emails to mimic natural behavior (engagement shows email providers the content is valuable).
Warmup Tuned to Your deliverability
EmailWarmup.com offers multiple email warmup algorithms — new accounts get a gradual volume ramp-up over 14-21 days, and distressed inboxes get aggressive repair to fix damage from spam sendcomplaints, bounces, or blacklists. Choose medium & fast speed (for new accounts) or slow speed (if you're already high in deliverability). The warmup preference wizard shows all options on a single screen (profile selection, speed, targets).
Personalized Warmup
We warm up your domain specifically for each email service provider. You can choose which ESPs you want to warm up — ignore ESPs with no issues. You can include or exclude specific providers (Outlook, Apple Mail, MS 365, Zoho, Gmail, G Suite, Yahoo, SMTP). Moreover, you can control how much warmup volume each provider receives or choose auto-distribution. Also, these warm-up emails can be sent in the same language as your audience.
DNS Records Checked, Verified, Fixed
Missing SPF records, broken DKIM signatures, or incorrect DMARC policies kill your deliverability — no matter how long you run warmup. Our domain authenticator walks you through adding/fixing SPF, DKIM, and DMARC DNS records and validates them. For each mailbox, trigger SPF, DKIM, DMARC, and blacklist checks. IP Blacklist Report lists major blocklists, shows Good/Bad status, and helps pinpoint reputation issues across many RBLs.
