Spam Checker. Land in the inbox.
Paste an email or text campaign and see exactly which words trip Gmail, Outlook, and carrier filters. No sign-up, and nothing you paste ever leaves your browser.
Scan your message
Results update as you type
Content is one deliverability signal among many. Authentication (SPF, DKIM, DMARC), sender reputation, list hygiene, and complaint rate matter just as much. This scan runs entirely in your browser.
Subject line tester
See where each client cuts you off, before your reader does
Nothing leaves your browser
The whole scan runs on your device. Paste a client's campaign without uploading it to anyone, including us.
Two tiers, not one alarm
Most checkers flag "soon" and "here" as hard failures. We separate real triggers from words that appear in normal writing, so you fix what matters.
Rewrites, not just warnings
Every flagged phrase comes with a specific replacement, so you know what to write instead of guessing.
Clean copy is step one. Sending it is step two.
Sales Nest sends your campaigns, texts back missed calls, and books the replies straight onto your calendar. One flat price, every feature included.
