EmailWarmup launched the first Chrome extension that tracks email placement in real time. The spam checker shows marketers whether their emails reach inboxes or get filtered to spam folders.
The extension addresses a critical blind spot in email marketing. Most marketers rely on open rates to gauge the success of their deliverability. EmailWarmup’s extension provides concrete data on actual email placement across multiple email providers.
“Marketers have been operating blind,” says EmailWarmup CEO Daniyal Dehleh. “This tool shows exactly what happens after you hit send.”
It saves you from doing an email deliverability test (that’s based on predictions) all the time before launching a campaign, and now you can know your email deliverability rate directly, without having to send test emails to different email accounts and understand where your emails are landing (inbox, promotions, or spam) manually.
How It Works
The Chrome extension monitors sent emails and reports placement results immediately. Users can see which emails succeeded and which failed before launching full campaigns.
The tool tests emails across major providers, including Gmail, Outlook, and Yahoo. Results appear within minutes of sending test emails.
Market Impact
Email marketing generates $42 for every $1 spent, according to industry data. Poor deliverability costs businesses millions in lost revenue. The new tracker helps companies identify problems before they scale.
Current spam checkers only predict potential issues. EmailWarmup’s extension tracks actual outcomes.
Availability
The Chrome extension is available at www.emailwarmup.com/email-spam-checker. The basic spam checker is free. Advanced real-time tracking requires a Maxify Inbox (by EmailWarmup) subscription.
The extension works with Gmail, Outlook, and other major email clients. Installation takes under a minute.
