In 2025, email marketing tactics need to evolve to address new challenges. As iOS Mail Privacy Protection continues to evolve and inbox filtering algorithms get tighter, pinning your hopes on old tricks can mean losing performance, conversions, and revenue.
Today’s marketers on Salesforce Marketing Cloud (SFMC) must confront a central question: how do you remain relevant in a privacy-first world?
In this blog, we’ll address the effect of iOS Mail Privacy, detail how to enhance SFMC deliverability, provide testing strategies still effective, dissect the new email success metrics for 2025, and much more.
What Is iOS Mail Privacy, And Why Does It Matter For SFMC?
iOS Mail Privacy Protection (MPP) from Apple, expanded up to iOS 17+, limits senders from seeing open rates and IP addresses.
Why it’s vital for Salesforce Marketing Cloud:
- Open Rates Aren’t What They Used To Be: Apple preloads tracking pixels, erroneously boosting open rates.
- Automations Due To Opens Become Ineffective: Paths in SFMC, initiated due to “opens”, will never depict true user engagement.
- Segmentation Gets Disrupted: Applying open behaviour for targeting causes sends to go to waste and perform terribly.
What Is SFMC Deliverability, And What Are The Best Practices For 2025?
Deliverability is your capacity to hit the inbox rather than the spam folder. In SFMC, it is dictated by sender reputation, engagement with emails, and quality of content.
Best practices to deliver better SFMC emails:
Authenticate your domain (SPF, DKIM, DMARC):
- Correct authentication enhances trust with ISPs and avoids spoofing.
Take care of list hygiene:
- Delete inactive users, bounces, and non-engaging subscribers to save your sender score.
Warm up your IP/domain:
- Slowly increase give-out volumes for new domains/IPs to establish sender credibility over time.
Send clean, non-spammy email content:
- Steer clear of spam trigger terms, too much use of exclamation marks, and misleading subject lines.
Track performance metrics:
- Observe bounce rates, spam complaints, click-through rates, and unsubscribe rates with SFMC dashboards.
Testing Strategies That Remain Effective In A Privacy-First World
Even with the evolution of tracking, A/B testing email remains a high-impact tactic in SFMC.
A/B test smartly that marketers should still execute:
Click-through rate (CTR) testing:
- Opt for clicks, rather than opens. Test CTA locations, text vs. button CTAs, and link orientations.
Subject line vs. preheader optimisation:
- Create pairs that prompt clicks and effectively give the key takeaways from the content of the email.
Layout testing:
- Compare single-column vs. multi-column, image-dense vs. text-empty, or long vs. short formats.
Send-time optimisation:
- Test various days/times according to click patterns, not open data, for better engagement.
New Email Success Metrics To Utilise In 2025
Old metrics, such as open rate, are obsolete. Marketers require metrics that relate to actual engagement and ROI in 2025.
Most important email success KPIs that count now:
Click-to-open rate (CTOR):
1. Maximises the engagement of your email by those who open it. Prioritise here for precise performance measurement.
Revenue per email (RPE):
2. Monitors direct money returns from your campaigns—perfect for e-commerce and B2B sales funnels.
Conversion rate:
3. Track the % of subscribers who finish your main call-to-action. This can be shopping or form submissions.
List growth rate:
4. Examine net growth in subscribers to gauge how effective your lead capture efforts are.
Unsubscribe and complaint rate:
5. Reveals ineffective audience targeting or oversending. Keep complaint rates below 0.1% to avoid deliverability issues.
How To Read an Inflated Open The Right Way
Thanks to Apple Mail’s default image preloading, most marketers are experiencing artificially inflated open rates.
Here’s how to align your analytics approach:
- Downplay open-driven triggers in SFMC: Modify journey logic to fire off clicks or purchases instead.
- Employ UTM tags for link tracking: This provides complete visibility in Google Analytics or Salesforce Datorama.
- Segment on click behaviour, not opens: Assess active contacts on link engagement and downstream activity.
- Add click-worthy features: Add clickable banners, polls, and interactive photographs that elicit real engagement.

What’s New In Inbox Filtering In 2025?
Inbox filtering is now AI-driven. Email platforms now consider user intent, history, and engagement when deciding where to place emails.
What to understand in the new filtering features:
1. AI tracks sender consistency:
Unpredictable sends, less engagement, or unexpected surges can trigger spam filters.
2. Domain reputation matters now more than ever:
ISPs now review the domain name (not only the IP address) to assess trust.
3. Content quality affects inbox placement:
Poorly formatted emails, dead links, or spammy text are marked more quickly.
4. Mobile optimisation is obligatory:
Most filtering systems currently verify for responsive design as a part of user experience scoring.
