Subject lines are the first thing a reader sees when it comes to email. Subject lines need to catch your customer’s attention in order to get them to open it, make clicks, and get the conversion. A good review request subject line will include something to make the person reading it want to open the email and write the review. That could be an incentive offering, personalization (such a first name), emojis, or simply just getting to the point and asking for the review. 

If you are needing some subject line inspiration or just need a subject line you can grab and use in an upcoming review invitation email campaign, check out this list of 20 subject lines.
