Frequently Asked Questions
Find answers to common questions about email verification.
Why are subject lines so important in email campaigns?
Subject lines are the first thing people see. A clear and relevant subject line increases open rates and sets expectations for the email.
Do welcome emails need different subject lines than sales emails?
Yes. Welcome emails should sound friendly and personal, while sales emails should focus on value, urgency, or a clear benefit.
What makes a good newsletter subject line?
Good newsletter subject lines are short, clear, and give a reason to open the email, such as useful tips, updates, or exclusive content.
Should sales email subject lines include discounts or offers?
They can, but only if it feels natural. Overusing discounts can reduce trust and lower long-term engagement.
How long should an email subject line be?
Ideally, keep subject lines under 40–50 characters so they display well on mobile devices.
