Do DKIM selectors affect email reputation?

Marketer from Email Geeks shares that a common machine learning approach is to incorporate as many data points as possible, suggesting anything and everything could feed into reputation unless evidence indicates otherwise.

Email marketer from MailerLite Blog implies that while DKIM itself improves deliverability and trust, they do not specifically mention DKIM selectors having a direct impact on email reputation but focus on the general DKIM setup.

Email marketer from Postmark shares about the general importance of DKIM, SPF and DMARC for deliverability, they mention DKIM selectors are to tell the receiving server which public key to use to verify the email. However, they do not mention if the selectors affect email reputation.

Email marketer from GlockApps shares DKIM contributes to domain reputation but does not elaborate specifically about DKIM selectors having an individual impact on reputation, focusing on the importance of overall email authentication.

Marketer from Email Geeks shares that using per-selector reputation would disrupt DKIM best practices, specifically regular key rotation.

Marketer from Email Geeks shares that the 5322.From domain and the DKIM signing domain are what some large mailbox providers consider a reputation data point.

Marketer from Email Geeks adds that sending IP could also be included as part of the data set for IP reputation.

Email marketer from SparkPost shares that properly configured DKIM authenticates email, which contributes to a positive sending reputation. However, they don't specify selectors as an individual element of reputation.

Email marketer from SendGrid Blog explains that DKIM (DomainKeys Identified Mail) is an email authentication method designed to verify the sender's domain and protect against email spoofing, but there's no specific mention of selectors affecting reputation; it focuses on domain reputation influenced by authentication as a whole.

Expert from Email Geeks explains that you are absolutely not supposed to use selectors for reputation, but some ISPs do, noting that machine learning may identify selectors as a data point.

Expert from Spam Resource, John Levine, explains that while DKIM authenticates a message, the selector itself is primarily a technical mechanism for key rotation and doesn't directly influence email reputation. Reputation is generally tied to the domain (d=) and sending IP.

Expert from Word to the Wise, Laura Atkins, explains that DKIM selectors are for key rotation and that the domain in 'd=' is the one which receivers use to learn reputation about mail. The key itself does not affect reputation.
