Cold email checker
Paste a cold email to see what helps or hurts it reaching the inbox. These are the checks SendPath's editor runs as you write.
Write variables as {{first_name}}. In SendPath, {{unsubscribe_url}} and {{physical_address}} are filled in for every contact: a one-click unsubscribe link and your business address.
Required to send
Unsubscribe link
Add {{unsubscribe_url}} - every email needs a one-click way out, and Gmail and Yahoo require it for bulk mail.
Postal address
Add {{physical_address}} - the law (CAN-SPAM) requires a postal address in every commercial email.
Hurts inbox placement
Spam-trigger words
"free", "only a few left", "guaranteed", "100% free", "act now" - filters and readers flag these. Say it plainly instead.
Subject line
The subject has "FREE" in capitals; an "!"; a "Re:" or "Fwd:" on a first message - deceptive, and filters know it.
Link safety
bit.ly hides where the link goes - spam filters distrust short links.

A question to answer
End with one simple question ("Worth a quick chat?"). Replies tell inbox providers people want your mail.
Variety (spintax)
Every contact gets identical wording. At volume, vary a greeting or a line with {{RANDOM | Hi | Hello}} so emails don't all look the same to filters.
In SendPath these checks run as you write, and the pre-send gate won't send an email that fails a required one.
What it checks
What helps, what hurts, and what's required
Required to send
- Unsubscribe link
- A one-click way out. Gmail and Yahoo require it for bulk mail.
- Postal address
- The law (CAN-SPAM) asks for one in every commercial email.
- Variables written correctly
- Every {{variable}} has both its braces, so nobody gets a broken greeting.
Hurts inbox placement
- Spam-trigger words
- Hype that filters and readers both distrust.
- Subject line
- Short, with no words in capitals, no "!" or emoji, and no fake "Re:".
- Links
- One link or none in a first email, and no short links, bare IP addresses or disguised links.
- Length and tone
- Under 200 words, without shouting or a row of exclamation marks.
Gets more replies
- Personalisation
- A {{first_name}} or a line about their company makes each email different.
- A question to answer
- Ending on one simple question makes replying easy.
- Variety
- Spintax like {{RANDOM | Hi | Hello}} so emails don't all look the same at volume.
FAQ
Questions, answered
Is it really free?+
Yes. There's no sign-up, and it runs in your browser: nothing you paste is sent or saved.
Why does it ask for {{unsubscribe_url}} and {{physical_address}}?+
Every cold email needs a way to unsubscribe and a postal address. In SendPath you write these two variables once, and each contact gets their own one-click unsubscribe link and your business address.
Does a high score mean my email will reach the inbox?+
No. The checker looks at the email itself. Where it lands also depends on your domain's DNS, your mailbox's reputation and warm-up, and your list. SendPath checks those before every campaign as well.
How is the score worked out?+
It starts at 100 and loses 10 for each warning and 3 for each tip. While a required check fails, it's 40 at most.
