Cold email checker: spam words, length, links and opt-out
A cold email gets read when it is short, personal and plain. Paste yours with its subject line: the checker flags spam-trigger words, shouting, too many links, missing personalisation and a missing opt-out, and tells you what to change.
What the checker looks at
- Subject line: length, capitals, exclamation marks and words that look like advertising.
- Length: short emails are easier to read and answer on a phone.
- Links and images: one link at most in a first email; none is often better.
- Personalisation: a name, the business name or something specific about them.
- A question: an email that ends with a simple question gets a simpler answer.
- Opt-out: a line that lets the recipient say no. In the EU and the US it is expected for business emails.
A first email that gets answers
Say who you are in one line, show you looked at their business, offer one concrete thing, and ask one easy question. Leave the brochure, the pricing and the long signature for the second email.
Write to businesses that need you
LeadsIt shows signals for each business it finds, such as no website, an outdated website or few reviews, so your first line can be about them. Packs from $6.90, no subscription.
Frequently asked questions
Which words trigger spam filters?
No single word sends an email to spam: filters weigh many signals, starting with your domain setup and sending history. Advertising words, all caps and many exclamation marks add to the risk, so the checker flags them.
How long should a cold email be?
Short enough to read on a phone without scrolling. The checker flags emails that are much longer than a few short paragraphs.
Do I need an unsubscribe link in a cold email?
You need a clear way to opt out. A sentence such as “Reply no and I won’t write again” works for one-to-one emails; bulk tools usually add a link. Rules vary by country, so check yours.
Is my email stored?
No. The analysis runs in your browser and nothing is sent to LeadsIt.
