Test subject lines and spam risk before sending
The Email Subject Line Tester scores a subject on the mechanical factors that correlate with opens: length in characters and words — mobile clients truncate somewhere around 40 characters — plus spam trigger phrases, all-caps runs and excess punctuation. No tool can guarantee an open rate, but this one catches the avoidable mistakes, like a subject that gets cut off exactly where the offer was, before a campaign goes out to a full list rather than after.
The Email Spam Checker scans your complete email copy for the trigger words and patterns filters weigh against you — “act now”, “100% free”, strings of exclamation marks. Modern spam filtering looks at far more than word lists, but flagged phrases still add up, and rewriting a handful of them is the cheapest deliverability improvement available. The check runs in your browser, so an unannounced product launch or a sensitive internal memo is not passed through a third-party analysis service on its way to being checked.
Generate a signature that survives email clients
The Email Signature Generator builds a clean HTML signature — name, role, company, phone, links — that renders correctly in Gmail and Outlook. That is harder than it sounds: email clients ignore most modern CSS, so a signature has to be constructed from the small, old-fashioned subset of HTML they all still respect. Fill in your details, copy the result, and paste it into your mail client’s signature settings once; every message after that carries it automatically.
