Apple's Mail Privacy Protection (MPP) has changed how cold email tracking works. It blocks tracking pixels, hides IP addresses, and preloads email content, making open rates unreliable. Here's what you need to know:
Cold email strategies must now prioritize real user actions over outdated metrics. This shift requires smarter tools and refined tactics to maintain effectiveness.
Before Apple Mail Privacy Protection (MPP) shook things up, cold email tracking was a straightforward, data-packed process. Email marketers had access to detailed insights that shaped their campaigns and strategies. Understanding how things worked before MPP highlights just how much has changed since its introduction.
At the heart of pre-MPP email tracking was the tracking pixel - a tiny, invisible image embedded in emails. These pixels were uniquely coded for each recipient or campaign. When someone opened an email, their email client would automatically load the pixel, sending a signal back to the sender's server to confirm the email had been opened.
Other tools, like read receipts and browser extensions, added extra layers of tracking. HTML image tags were also employed to monitor engagement, though these methods raised privacy concerns and required careful handling to avoid crossing ethical boundaries.
Open rates were the cornerstone of cold email success before MPP. They influenced nearly every decision marketers made, from A/B testing subject lines to setting up automated follow-ups. For example, if an email was opened but left unanswered, follow-ups could be triggered automatically. Open rate data also helped segment email lists, grouping recipients into categories like "highly engaged" or "low engagement", which allowed for more personalized and effective messaging.
Marketers focused heavily on elements like subject lines, sender names, and preheaders to improve open rates. This was especially critical because, in 2021, Apple devices accounted for about 52% of all email opens - a huge segment of the audience.
Tracking pixels provided a treasure trove of data, offering deep insights into recipient behavior and preferences. This information helped marketers fine-tune their campaigns and better understand their audience. Here’s a breakdown of the data typically collected:
Type of Data | Description |
---|---|
Email opens | Logged each time a recipient opened an email. |
Location data | Captured the geographic location where the email was opened. |
IP address | Recorded the device's IP address used during the open. |
Device info | Detailed information about device type, operating system, browser, and screen resolution. |
Email client | Identified the specific email application used. |
Timestamps | Provided exact dates and times of email opens. |
Subscriber interaction | Tracked clicks on links, buttons, images, and time spent reading the email. |
Conversions | Monitored completed actions or purchases after interacting with the email. |
This data - ranging from timestamps to geographic location - allowed marketers to optimize everything from email design to sending times. Each interaction was logged as a separate event on the sender's server, creating a detailed behavioral profile for each recipient. These insights formed the backbone of sophisticated email marketing strategies, making the post-MPP landscape a much tougher environment for marketers to navigate.
Apple Mail Privacy Protection (MPP) has shaken up the cold email world by making open tracking unreliable and inflating metrics. This shift forces cold email professionals to rethink their strategies from the ground up.
With MPP turned on, Apple reroutes emails through its proxy servers, automatically downloading all email content - including tracking pixels - before the recipient even opens the message.
"Mail Privacy Protection stops senders from using invisible pixels to collect information about the user. [It prevents] senders from knowing when they open an email, and masks their IP address so it can't be linked to other online activity or used to determine their location." - Apple
This automatic pre-loading creates "opens" that aren't real, leading to inflated open rates. Considering that nearly 50% of subscribers use MPP and Apple devices accounted for about 52% of email opens in 2021, many campaigns are now seeing a big jump in open rates that doesn’t reflect actual engagement.
The numbers tell the story. Data from Omeda shows that unique open rates nearly doubled within six months of MPP being implemented. This makes it nearly impossible to separate genuine user interest from automated activity, rendering open rates useless as a measure of engagement.
MPP also hides recipients' IP addresses, stripping away key information like their location, device type, and browsing context. For cold email marketers, this means losing critical insights that were once used for personalization and targeting.
Timing is another casualty. Before MPP, marketers could track when someone opened an email to understand optimal engagement windows. Now, the "open" timestamp simply reflects when Apple’s servers pre-loaded the email, not when the recipient actually looked at it.
These issues with open tracking have created a ripple effect, introducing new challenges for cold email campaigns.
The unreliable open rate data caused by MPP has upended traditional cold email strategies, creating hurdles across several areas.
In short, Apple’s MPP has forced marketers to rethink their reliance on open rates and adapt to a new, more challenging landscape for cold email tracking.
The game has changed, but cold email isn’t going anywhere. Smart marketers are shifting gears, focusing on metrics tied to real human actions, and rethinking strategies based on dependable data. Here’s how you can refine your cold email campaigns in this new landscape.
Since 75% of email opens are now artificially inflated by Apple’s Mail Privacy Protection (MPP), open rates have lost their value. Instead, prioritize metrics like clicks, replies, and conversions - actions that reflect genuine engagement.
You can also combine these metrics - like clicks, conversions, and time spent on your site - into an engagement score. This gives you a more complete picture of recipient behavior than any single metric.
With open rates no longer reliable, the traditional A/B testing playbook needs a refresh. Shift your focus to clicks and replies for more accurate insights.
Another tactic? Send new campaigns as replies to earlier emails. This keeps the conversation going while minimizing the impact of subject line variations.
While refining engagement metrics is essential, ensuring your emails actually reach inboxes is just as critical.
Artificially inflated open rates can hide serious deliverability problems. Your campaign might look fine on the surface, but recipients may never even see your emails. That’s why staying on top of domain health is more important than ever.
"Yes, your list sizes might go down as you clean up your email list. But your engagement will go up. Instead of sending to 60,000 people that may or may not care what you have to say, you're going to send to 30,000 people that definitely want to hear from you, and that's super valuable."
Aim for deliverability rates between 90% and 98% for the best results. High deliverability ensures your emails reach inboxes and validates the engagement metrics you’re now relying on. As Carin Slater explains:
"Deliverability is a measure of the health of your email marketing program, so it's important to do regular check-ups on your domain, IP, and authentication in particular to make sure you're up-to-date, just like how we all go to the doctor each year."
The challenges brought by Apple Mail Privacy Protection (MPP) have reshaped how businesses approach email tracking and deliverability. Traditional methods no longer work as they once did, and relying on consumer email providers for cold outreach is quickly becoming outdated. To succeed in this new landscape, businesses need infrastructure solutions designed specifically to handle privacy-first regulations while maintaining high deliverability standards.
MPP has introduced significant hurdles: it blocks tracking pixels, masks IP addresses, and severs the connection between email opens and user activity. As a result, your cold email infrastructure must adapt to these limitations and ensure your messages don't end up in spam folders.
Shared infrastructure solutions offer a practical way forward. Unlike managing your own email servers or depending on consumer email providers, these solutions provide a more reliable foundation for deliverability, especially when traditional metrics like open rates are no longer viable.
The key is to choose infrastructure tailored for cold outreach. Generic email tools can't handle the complexities of high-volume campaigns, domain management, or the technical requirements for maintaining deliverability. Specialized systems streamline the setup process while ensuring essential authentication protocols - like SPF, DKIM, and DMARC - are in place to build trust with inbox providers.
This shift has paved the way for tools like Mailforge.
Mailforge was built with cold outreach in mind, and over 10,000 businesses already rely on it to tackle MPP-driven challenges. Its shared IP setup distributes mailbox accounts across a vast network, ensuring better deliverability and scalability for cold email campaigns.
