Do email providers track clicks on verification links versus other links for deliverability?

Summary

Experts and marketers generally agree that email providers track user engagement, including clicks, as a factor in determining email deliverability and filtering decisions. While user engagement data, including click-through rates, are considered important signals, none of the sources definitively confirm whether email providers specifically differentiate between clicks on verification links versus other types of links for deliverability purposes. Emphasis is placed on overall engagement, sender reputation, and authentication standards (SPF, DKIM, DMARC) as critical factors influencing deliverability. Additionally, the importance of adhering to good permission practices to maintain positive user perception and improve deliverability is highlighted.

9Marketer opinions

Experts and marketers generally agree that email providers track user engagement, including clicks, as a factor in determining email deliverability. However, there is no consensus on whether email providers specifically differentiate between clicks on verification links versus other types of links. Some sources suggest that email providers prioritize overall engagement metrics, while others indicate that B2B filters rely more on sender reputation than engagement. A key point is that double opt-in is primarily for the sender's benefit, not the mailbox provider's. Several sources emphasize the importance of maintaining high engagement rates and following best practices for sender reputation to ensure optimal deliverability.
