Cold Email Subject Line & Opener Grader
Paste a subject line and opening line. Get an instant score on length, spam-trigger words, personalization, and vague-opener clichés — plus specific fixes.
How we tested this: We tested it against a deliberately weak email ('I hope this email finds you well... my name is...') and a strong one — it correctly scored them 20-25/100 and 100/100, flagging the exact clichés and spam triggers in the weak version.
This grader runs a fixed set of rules — it can't judge whether your line is actually relevant to the recipient. Use it to catch obvious mistakes, not as a final verdict.
