Free email spam checker

• Trigger phrases in four groups: money and offers (“free gift”, “lowest price”), pressure (“act now”, “limited time”), hype (“guaranteed”, “once in a lifetime”) and phrases that look like spam (“dear friend”, “congratulations”).
• Fake reply subjects such as “Re:” or “Fwd:” on a first email.
• Unfilled merge fields like {{first_name}} or [Company].
• Shouting: words in capitals (common acronyms like CEO or CRM are ignored) and stacked exclamation marks.
• Links and length: more than one link, or a body longer than people read on a phone.

Words are the easy part. Mailbox providers decide mostly on who you are and how people react to your mail. Gmail and Yahoo ask senders to keep spam complaints below 0.3%, and bulk senders must authenticate with SPF, DKIM and DMARC.

Before you send, check your domain with the DMARC checker, then send to people who have a reason to hear from you now. That is what keeps complaints low.

1. Replace each flagged phrase with a plain, specific fact: what you saw, what you do, what it changes.
2. Lead with the reason you are writing to this person now, such as a new role or a post they engaged with.
3. Ask one easy question instead of pushing a link.
4. Fill or remove every merge field, then read it on your phone.
