As an email marketer, you probably use open rate as a primary metric to measure the performance of your email campaigns. After all, high open rates indicate that your emails are being sent to your customer at the right time with the right subject line. But after the launch of the iOS 15 email updates, the way you leverage email open rates may change.
What are the iOS 15 email updates?
There are three primary updates in iOS 15 that will affect your email marketing campaigns:
Mail Privacy Protection, which requires iOS 15 users to enable explicitly, will reduce the accuracy of email open rates by stripping email trackers and masking your customers' IP address
iCloud+ will come with an additional 'Private Relay' feature preventing you from tracking Safari users on your website
Hide My Email will allow your customers to replace their real email address with a proxy that can be changed at any time
Best email marketing practices for iOS 15
As of 2021, Apple Mail holds an 11.5% market share of all email clients globally. This is a significant size of your customer base. Here's how you can tweak your email marketing strategy to prepare for this change:
1. Revisit your email open rate goals and benchmarks
The most significant impact of iOS 15 on email marketing is that you will no longer be able to tell who or how many customers are opening your emails. This means your current email open rate benchmarks, built on historical data, will need to be changed for iOS 15 users.
We strongly urge email marketers to create new customer segments consisting of only iOS 15 users and observe the email performance for these segments in isolation. This will help you set up new benchmarks accurately and ensure your other customers' data remains unaffected.
2. Move away from email open rates to other engagement metrics
It is time to stop considering email open rate as the leading indicator of your email marketing performance. You can instead use the following metrics to gauge what's working and what's not:
Number of clicks and click-through rates (CTR)
Higher CTR and conversion rates will indicate that your email was sent to your customer segment at the right time and had the right content. Whereas an increase in unsubscription rates will imply bad timing and irrelevant email content.
Perhaps the iOS 15 email update is a blessing in disguise for email marketers. A/B tests on subject lines are currently gauged by measuring either open rates or click-to-open rates (CTORs). But now, email marketers will have to measure the impact of subject lines based on more important metrics like conversions.
Instead of asking yourself, "Will the customer open this email?" you'll now have to ask yourself, "Is this email relevant to the customer?"
It would be best if you increased the emphasis on analytics and insights to send relevant email communication, resulting in more clicks and higher conversion. Observe your customers' actions on your app or website, and leverage this to send contextual emails.
For example, let's say a customer searches for "gardening accessories" in your search bar, sees a few product listings, and exits your mobile app or website. After a slight delay, you can send an email mentioning the search term in the subject line. You can also improve this further by adding the top product listings leading the customer to your mobile app or website. MoEngage customers can use a combination of Dynamic Product Messaging and the Email Suite to send personalized emails.
3. Customer segmentation criteria will have to evolve
So far, you must have relied on the "email open" action or IP addresses to segment your customers, but now you’ll need to use different criteria going forward.
Let's say you have exclusive rights to stream an upcoming major Football tournament. Earlier, if you wanted to create segments of customers who showed an interest in Football tournaments, you could consider those who opened your emails. Now, you'll have to change the filtering criteria to customers who actively subscribed for the tournament in the past.
While this approach will reduce the size of the target audience for your promotion, you can expect higher conversions because these are customers who've taken an action on your mobile app or website instead of just opening your email.
We believe the iOS 15 email updates will improve your segmentation habits. Creating customer segments based on your customers' personalities, lifestyles, beliefs, and choices will now gain more prominence. These 'Affinity Segments' will help you optimize your email campaigns by sending them relevant and timely communication.
For example, you can:
Create a segment of customers who listen to Madonna’s albums more often than others. This will let you send email announcements of new, similar albums on your audio streaming platform
Filter customers who book cab ride from your mobile app between 10 AM to 12 PM at least 40% of the time, enabling you to send emails with special coupons in the same time bracket
Find the bottom 20% of your customers who book hotels on a weekday, and send them discounts via emails to incentivize weekend bookings
View the top 10% of your customers who read political news, and send them timely alerts of breaking news via emails
4. Think of a fresh approach for location-based email marketing
Since Apple will remove all email trackers from your email when your customer accesses it via the Mail app on devices running iOS 15, you'll need a new approach to location-based marketing campaigns.
It is important to note that the removal of the tracking pixel does not hamper the viewing experience. Your customers will still be able to view all the email content you've added. The look and feel of your email (even those built on HTML email templates) will remain unchanged with this update.
Additionally, we also believe email deliverability will not be hampered by this update.
There are two ways you can capture location information. The first could be a soft ask during your onboarding process. You can leverage in-app interstitials on your mobile app for this. The second could be after your new customer has experienced their first 'aha moment'. This could be listening to their first song, purchasing a product, or booking a ride. Both these approaches can prove effective in capturing your customers' location information. We suggest you run A/B tests and find the right fit for your product. MoEngage customers can use the Intelligent Path Optimizer to run these tests and take the right decision.
