55+ Best welcome email subject lines

Welcome emails are among the most frequently opened, and for a good reason! When newly subscribed prospects join your mailing list, they expect a warm welcome from you and perhaps even a special discount for their first purchase.

This presents a fantastic opportunity for marketers to increase conversions and boost sales. Additionally, the welcome email series is the perfect starting point in a buyer's journey toward becoming a loyal customer. It all begins with the subject lines.

To provide a solid foundation for your series, we're sharing welcome email subject lines to kickstart a delightful conversation with your prospects.

Welcome email subject lines for SaaS

Getting visitors to sign up for a free trial or even a paid subscription is only the beginning. Next, you must get them excited enough to log in and use it. Otherwise, you’ll end up with a useless prospect contact.

So, that’s precisely what you want to do in your SaaS welcome emails – engage and interest the visitor so that they immediately hop into your product, already knowing how to use it a bit.

Take some subject lines to help you craft such an email:

Get ready to boost productivity

Special offer email. Provide an exclusive discount or promotion to motivate new subscribers to purchase repeatedly.
