What the experts say3Expert opinions
Expert from Email Geeks shares that just because an email address is deliverable does not mean that person signed up for your mail and explains it’s likely someone gave an address that didn’t belong to them, which ended up getting the client listed. Overall, though, she says it’s an old open source project and it should have zero impact on deliverability.
Expert from Word to the Wise explains that a domain's reputation is often viewed holistically across different channels. If a domain gains a reputation for sending SMS spam, this can impact how email providers view email from that domain, leading to filtering or blocking. This is because the domain is seen as engaging in questionable practices overall.
Expert from Word to the Wise explains that a primary goal of spam filtering is to improve customers’ experiences by minimizing abusive messages, therefore, providers can and do consider related or associated factors for making blocking or filtering decisions.
What the documentation says3Technical articles
Documentation from ietf.org answers that DMARC focuses on email authentication, it indirectly relates to overall domain reputation. By implementing DMARC, organizations protect their domain from email spoofing and phishing attacks. This helps maintain trust with recipients and ISPs, contributing to a better sender reputation over time.
Documentation from Spamhaus explains that while they primarily focus on email-borne spam, they acknowledge the growing interconnectedness of communication channels. If a domain is heavily abused in SMS spam campaigns, and that abuse is linked to malicious activity also observed in email, it could potentially influence their assessment of the domain's reputation.
Documentation from Sourceforge explains that Razor is a distributed, collaborative, spam detection and filtering network. While primarily focused on email spam, the principles it uses (identifying and reporting spam patterns) could, in theory, be applied to other communication channels. High rates of spam reports across multiple channels could contribute to a domain being flagged by Razor or similar systems.
