Email subject line examples

Locked in: renew now before prices go up

This subject line encourages users to renew or upgrade early due to an upcoming price increase. The opportunity to maintain current rates may persuade those on the fence to take action.

This one is extremely good for SaaS, memberships, or anything with a renewal window.

Our commitment to quality and value: price change announcement

A softer approach, with pricing changes, put the focus on quality and customer outcomes.

Customers feel reassured by the reminder of what the brand stands for.
