How Apple Mail Privacy Impacts Cold Email Tracking
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:
- Open rates are inflated: MPP preloads emails, marking them as "opened" even if users don’t view them.
- Lost data: Marketers can no longer access recipient location, device type, or real engagement times.
- Shift in focus: Metrics like click-through rates, reply rates, and conversions are now more reliable indicators of success.
- Challenges: Automated follow-ups, A/B testing, and list segmentation based on opens no longer work effectively.
- Solutions: Use privacy-compliant tools like Mailforge, focus on clicks and replies, and ensure strong deliverability practices.
Cold email strategies must now prioritize real user actions over outdated metrics. This shift requires smarter tools and refined tactics to maintain effectiveness.
How Cold Email Tracking Worked Before MPP
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.
Traditional Open Tracking Methods
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.
The Role of Open Rates in Cold Email Campaigns
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.
Data Collected Before MPP
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.
How Apple Mail Privacy Protection Affects Cold Email Tracking
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.
How MPP Disrupts Open Tracking
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.
Challenges for Cold Email Campaigns
The unreliable open rate data caused by MPP has upended traditional cold email strategies, creating hurdles across several areas.
- Follow-up sequences: Automated follow-ups based on opens now misfire, either targeting people who never saw the original email or spamming engaged recipients with redundant messages.
- A/B testing: Testing subject lines, sender names, or timing based on open rates is no longer reliable. Marketers now have to lean on click-through rates and conversion metrics, which provide smaller data sets and may miss nuanced engagement trends.
- List segmentation: Classifying recipients as "highly engaged" or "low engagement" based on opens is no longer effective. Marketers must pivot to using click data, website visits, or even manual methods to segment their lists, which demands more time and resources.
- Deliverability monitoring: Inflated open rates make it harder to detect actual deliverability issues. Campaigns might appear successful due to Apple's pre-loading, even if emails aren't reaching non-Apple users effectively.
- Personalization: Without access to location and device data, personalization efforts take a hit. Campaigns that once tailored content based on these insights must now adopt a broader, less targeted approach, potentially reducing their impact.
- Budget and optimization: Teams can no longer rely on open rates to scale campaigns or measure success. Instead, they need more advanced attribution models to figure out what’s driving results. This slows down the process of identifying and refining winning strategies.
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.
How to Adjust Cold Email Strategies After MPP
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.
Focus on Reliable Engagement Metrics
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.
- Click-through rates (CTR): Clicks require deliberate action, making them a strong indicator of interest. Tracking how many recipients click on links in your emails can reveal who’s genuinely paying attention.
- Reply rates: A reply is one of the clearest signs of engagement. However, the average reply-to-open rate dropped from 7.03% in May 2021 to 3.28% in May 2022, largely due to inflated open rates. This makes replies an even more valuable metric now.
- Conversion rates: Whether it’s filling out a form, booking a demo, or making a purchase, conversions show if recipients are taking the desired next step.
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.
Adjusting A/B Testing and Follow-Up Logic
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.
- Test subject lines by measuring clicks and replies instead of opens.
- Use larger test groups. Since clicks and replies occur less frequently than opens, increasing your sample size (e.g., a 50%-50% split) helps ensure your results are meaningful.
- Revamp follow-up sequences. Automate follow-ups to stop once a recipient clicks a link or replies. This prevents over-messaging engaged prospects while continuing to nurture those who haven’t acted yet.
- Segment follow-ups based on actions like "Didn’t Click" or "Didn’t Reply", rather than relying on open data.
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.
Maintaining Domain Health and Deliverability
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.
- Focus on inbox placement, not open rates. On average, email deliverability sits at 81%.
- Use authentication protocols like SPF, DKIM, and DMARC to verify your emails and avoid spam filters.
- Track your sender reputation with tools like Google Postmaster Tools and DMARC monitoring. Keep an eye on bounce rates, complaint rates, and delivery rates.
-
Clean your email list regularly. Remove inactive subscribers and invalid addresses to improve deliverability. As Carin Slater, Manager of Lifecycle Email Marketing at Litmus, puts it:
"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."
- Create content that encourages real engagement. Nearly 78% of survey respondents mark emails as spam if they "look like spam." Focus on delivering personalized, valuable content with clear calls-to-action.
- Warm up email accounts gradually. Without reliable open rates, warming up accounts carefully is key to avoiding spam filters.
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."

Using Infrastructure Solutions for Privacy-Compliant Cold Email
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.
Why Privacy-Compliant Infrastructure Matters
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.
