    The thinking

    What is a cold email checker?

    A cold email checker is a tool that scans your draft for the things that get it filtered or ignored, spam trigger words, salesy cliches, and formatting that reads as automation, and tells you before you hit send. Think of it as a spell check for deliverability and tone rather than for grammar.

    Spam is not one thing you fix with a word list. Inbox placement depends on your copy, your domain authentication, and your sending reputation together. Copy is the part you control on every single send. Clearing the obvious triggers will not save a cold domain, but leaving them in will sink even a healthy one, so this cold email checker focuses on what you can change in thirty seconds: the words and the shape of the message.

    It also flags what a generic spam word checker misses. The em dash that marks AI writing. The cliche opening line every prospect has read a hundred times. The wall of text no one reads on a phone. Those do not trip a spam filter, but they lose the human, and losing the human costs you the reply just the same.

    FAQ

    Deliverability questions people actually search

    Why are my emails going to spam? +
    Usually three things stack up: spammy copy such as trigger words, links and over formatting, weak domain authentication where SPF, DKIM and DMARC are not set, and a cold or over sent domain. Copy is the fastest to fix and the only one this checker scores. If your copy is clean and mail still lands in spam, the problem is almost always your domain setup or sending volume.
    How do you stop cold emails from going to spam? +
    Start with the copy: cut spam trigger words, drop links from the first email, keep sentences short, and lose the cliches. Then make sure your domain has SPF, DKIM and DMARC in place, warm the mailbox before sending, and keep volume low per inbox. This tool handles the first part and scores it for you.
    What makes a cold email spammy? +
    Trigger words like free, guarantee and act now, too many links, images or heavy formatting in a first touch, a subject that overpromises, and long dense paragraphs. Filters read all of it. This checker highlights each one in your draft so you can see exactly what is dragging the score down.
    Does an em dash hurt deliverability? +
    Not with spam filters, but it is one of the clearest tells that copy was written by AI, and prospects increasingly notice it. The checker flags every em dash so you can swap it for a comma or a full stop and keep the writing human.
    Is this cold email checker free? +
    Yes. No sign up, no card, and no limit. Your copy never leaves your browser.
    What is a good deliverability score? +
    Aim for the green band. A high score means you have cleared the obvious copy risks such as spam words, links, em dashes and long sentences. It does not guarantee the inbox on its own, since domain and volume also matter, but it removes the part of the problem that lives in the words.
