Frequently Asked Questions

Find answers to common questions about email verification.

What is a good reply rate for cold email outreach?

A targeted cold email campaign typically achieves a 3–8% reply rate. Highly personalised campaigns with tight ICP targeting and strong copy can reach 15–25%. If your reply rate is below 3%, revisit your ICP definition, your first line, and your value proposition before increasing volume.

How many follow-up emails should you send in cold outreach?

Send a minimum of 3 follow-ups and ideally 4–5 total touches. Research from Salesforce (State of Sales, 2024) shows that most B2B replies come after the second or third touch. A standard sequence runs 5 touches over 21 days.

Is cold email legal in 2026?

Yes. Cold email is legal in the United States under CAN-SPAM, in the EU under GDPR (using a legitimate interests basis for B2B), and in many other markets. Canada's CASL is stricter and requires implied or explicit consent. Every jurisdiction requires an opt-out mechanism in every email.

What should the subject line of a cold email say?

The subject line should be specific to the recipient and under 60 characters. Strong formulas include a question referencing their company, a trigger event mention, or a social proof reference. Avoid generic lines like "Quick question" and never use all caps or false urgency.

How long should a cold email be?

Keep cold emails under 150 words. Data from Boomerang and Lavender (2024) shows that emails between 50 and 125 words achieve the highest response rates. If your email exceeds 150 words, cut the company background and feature lists. Keep only the personalised opener, one value statement, and one CTA.
