While email authentication doesn’t directly guarantee a specific increase in “email opens,” it significantly impacts a crucial prerequisite: email deliverability. Here’s how it works:
The Link Between Authentication and Opens:
- Deliverability is Key:
- If your emails land in the spam folder, they’re unlikely to be opened. Email authentication (SPF, DKIM, DMARC) dramatically improves your chances of reaching the inbox.
- By proving your legitimacy, you gain trust with email providers, who are then more likely to deliver your messages.
- Reputation Matters:
- Email authentication contributes to a positive sender reputation. A good reputation signals that you’re a trustworthy sender, which further enhances deliverability.
- When email providers see authenticated emails from a reputable sender, they’re less likely to flag them as spam.
- Trust and Confidence:
- In some cases, especially with BIMI (Brand Indicators for Message Identification), authentication can display your brand logo in the inbox. This can increase recipient trust and confidence, potentially leading to higher open rates.
Important Considerations:
- Open Rate Limitations:
- It’s important to note that email open rates are becoming less reliable as a metric due to privacy changes like Apple’s Mail Privacy Protection (MPP).
- Therefore, while authentication helps get your emails into the inbox, it doesn’t guarantee that every email will be tracked as “opened.”
- Focus on Engagement:
- Beyond opens, focus on engagement metrics like click-through rates and conversions. These provide a more accurate picture of your email campaign’s success.
In summary:
- Email authentication is essential for improving email deliverability.
- Better deliverability increases the likelihood of your emails being seen and opened.
- While open rates themselves are becoming less reliable, authentication remains a critical factor in successful email marketing.
