Because they know who it is from
Sixty-four percent of subscribers (opens in a new tab) say that their biggest reason to open an email is the because of who it is from.
This is much more important than your subject line, offer, intro paragraph, and expected length. The reason for this is very simple: people can tell from past experiences if your emails are worth opening or not.
- If someone signs up for a lead magnet, they’ll expect (and likely open) your email with the lead magnet because the subject line directly mentions it.
- If someone buys something from you, they’ll expect a transactional email like an order confirmation or receipt, which they’ll probably open.
- If your email newsletter hints at an upcoming announcement, you can build excitement so more people open your announcement email.
Because your subject line promises them something or makes them curious
Thirty-five percent (opens in a new tab)of email recipients open email based on subject line alone, according to Convince and Convert.
That makes it one of the most important factors to consider when it comes to increasing your open rates.
If your subject line promises them things they want, like a special discount code, they’re more likely to open your email.
Because you send emails at the right time
23.8 percent of all email opens (opens in a new tab) occur during the first hour of delivery. After 24 hours, there is less than a 1 percent chance that your email will be opened and read.
This means even if you have the best subject line, you diminish your chances of your message being seen and opened if you send it at the wrong time.

Major problems with review request emails
- Low Open Rates: One common issue with review request emails is low open rates. This often stems from unappealing subject lines that fail to capture attention or timing that doesn’t align with when customers are most likely to engage with their inboxes.
- Low Conversion Rates (CR): Another challenge is low conversion rates, where customers open the email but don’t take action to leave a review. This can result from complex processes, unclear calls to action, or insufficient motivation for the recipient to respond.
How can you practice improving review request emails performance
1. Start with subject line to combat open rate
A well-crafted email subject line is crucial for several reasons. It serves as the initial point of contact between the sender and the recipient.
Make sure your review request is:
- Short: Typically around 61-70 characters, or up to 10 words, a subject line with this length can capture attention quickly while conveying the email’s purpose.

-
Emotional: Mixpanel found (opens in a new tab) that being appreciative and including nice words such as “thank you,” “thanks,” “please,” or “sorry” helps you increase open rates to 22.98%
On the other hand, being demanding will decrease your open rates.
For example: when using exclamation points, Mixpanel sees a fall in open rates to 10.92 percent.
-
Narrowed down who you’re talking to: Try to make use of these variables to make your request more relevant and resonant!
Tips: If someone buys something from you, they’ll expect a transactional email like an order confirmation or receipt
