SMS spam complaints can negatively impact email domain reputation and deliverability. Email providers and blacklists often correlate data across channels, so poor SMS practices can make them suspicious. Maintaining a positive reputation across all channels, including SMS, is crucial. The key is consistency and trust. Spamhaus acknowledges the interconnectedness of channels, so if SMS abuse is linked to malicious email, it can influence their domain reputation assessment. DMARC can indirectly help reputation, while Razor is a collaborative spam detection network that could apply its methods to other channels. A domain’s reputation is often viewed holistically. Remember that email validation may not verify that a recipient signed up for emails.

SMS spam complaints can affect email deliverability due to the holistic view email providers take of a domain's reputation across communication channels. Engaging in questionable practices in one channel, like SMS, can impact how email from that domain is treated. While Razor, an older open-source project, might not directly impact deliverability, providers consider related factors when filtering spam to improve user experience. Verification of email addresses may not be enough as the recipient may not be the actual owner of the email address.
Expert view
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.

SMS spam complaints can indirectly impact email domain reputation and potentially lead to blacklisting. Spamhaus acknowledges the interconnectedness of communication channels, where SMS abuse linked to malicious email activity can influence their domain reputation assessment. While DMARC focuses on email authentication and indirectly helps domain reputation, Razor, a collaborative spam detection network, could theoretically apply its spam pattern identification to other channels, including SMS, potentially contributing to a domain being flagged if high rates of spam reports are observed across multiple channels.

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.
