It's definitely concerning to see such a drastic drop in your email engagement rates, and you're not alone. While Google's recent email sender guidelines update might play a part, several other factors could be contributing. Also, I'd not use email metrics like opens and clicks as primary measures for marketing success, as they're often unreliable due to bot activities.
Possible reasons for your drop in engagement:
- Increased email volume: Did you send more emails in December and January compared to November? Email fatigue can set in if users receive too many communications, leading them to tune out.
- Content relevance: Was the content in your December and January emails as relevant and engaging as your November emails? Make sure your content aligns with your audience's interests and solves their problems.
- Segmentation and targeting: Are you segmenting your list and sending targeted emails based on user preferences and behavior? Generic, one-size-fits-all messages might not resonate with everyone.
- Deliverability issues: Check if your emails are landing in spam folders due to poor sender reputation or spammy content. Consider running a deliverability test to identify any issues.
- Apple Mail Privacy Protection (MPP): If you have a significant portion of subscribers using Apple Mail, MPP, which hides open rates on iOS devices, could be impacting your overall numbers.
- Google's email sender guidelines: While less likely the main culprit for such a dramatic drop, the new guidelines do emphasize sender reputation and user engagement. Maintaining good practices as outlined by Google is always crucial.
- Marketo Email Bot Filtering: Did you recently turn on Marketo's bot filtering feature? Turning it on and choosing to not log bot activities could lead to drop in email opens and clicks as Marketo would filter out the activities it thinks are coming from bots.
