How Email Emojis Affect Open Rates
I used to often wonder how email emojis affect open rates when you add them.
Does adding emojis in your email subject line affect your open and deliverability rates?
Particular how would emoji use in email subject lines directly make an impact on how many emails were opened?
Would such inclusion create greater attention for the unsuspecting casual email viewer, to a point where they were more likely to read my emails?
These are all great questions, and a company by the name of Return Path did a case study on this subject in recent years.
They selected the most popular holiday of every month during a calendar year (total 12 holidays were selected), and chose 3 popular emojis for each holiday.

How Email Emojis Affect Open Rates: Let’s Define the Problem
Return Path sought to find out how emojis in email subject lines were resonating with their subscribers.
Since emojis had become a very popular addition in digital communication, they were most highly used in personal communication like texts and social posts.
Increasingly used in email marketing campaigns, these emojis were starting to be used in email subject lines for email marketing campaigns.
Return Path explored the effectiveness of emojis in email subject lines, by identifying a significant holiday for each month and then tracking the use of emojis for that theme.
For a selected holiday of each month, Return Path gathered the following data for the most common emojis:
To demonstrate how emojis in subject lines compared to traditional text-only subject lines, Return Path showed these same metrics for all promotional emails sent during the promotional period. In addition, they compared emails with themes in the subject lines compared to holiday-related keywords.
To finalize their experiment, they highlighted the three most important emojis every month to show a starting point for testing your own email campaigns.
A Surprising Result
From the data I have examined, the results uncovered a surprising yet consistent trend that overall open rates increased when emojis were used in the email subject line.
This trend was consistent for every major holiday.
The Inbox Placement Rate (%) when adding emojis in the email subject line either increased or remained the same for the most important Holidays (Easter, Mother’s Day, Father’s Day, Independence Day, Halloween, Thanksgiving, Christmas).
However, in terms of popularity for the less important holidays (New Year’s Day, Valentine’s Day, St.Patrick’s Day) the Inbox Placement rate decreased when adding emojis in the email subject.
Also note that for every holiday, the READ Rates increased and the DELETED Before READING Rate decreased.
No doubt, one of the "Emoji Stars" is the Poop Emoji, he gets "opened" most of the time (here in September) - you can even see his READ rate and Inbox Placement Rate is higher than the others - but if you MUST use him just make sure "Mr. Poop" is used sparingly and with relevancy!
These trends certainly support using emojis in your email subject line.
