Use case
Onboard Free UserAbout this email
This onboarding email from Semrush thanks users for activating their trial and encourages them to start using the platform immediately to maximize their trial benefits. It features a structured layout with branded logos, images, and clear calls-to-action directing users to the dashboard and specific tools like Keyword Magic Tool, backlink analysis, and lead finder. The tone is friendly, motivational, and supportive, with added value through instructional resources and testimonials to boost user engagement and confidence.
Why this works
**Why this works.** The subject line "Don't put it off" names the actual friction point - procrastination on activation - rather than celebrating the activation itself, so it reframes the email as urgent action instead of confirmatory noise. The pattern here is "identify the next behavioral trap, not the past action completed"; you can lift it for any post-signup or post-trial-start email where users have activated but won't actually use the product.
