Should I be concerned about spoofing when using a different from domain than the subdomain configured in the ESP?

Email marketer from Neil Patel Digital explains that email spoofing is a technique used in spam and phishing attacks to deceive users into thinking a message came from a trusted source. Using a different 'from' domain can raise red flags and potentially be seen as spoofing if not properly authenticated.

Email marketer from GMass explains that deliverability issues can arise when using a different 'from' domain without proper setup. It is crucial to align your sending practices with authentication standards to avoid being flagged as spam.

Email marketer from Sendinblue explains that maintaining a positive domain reputation is vital for email deliverability. Using different 'from' domains without proper authentication can damage your domain's reputation, leading to increased spam classifications and reduced inbox placement.

Email marketer from ActiveCampaign explains that maintaining a good sender reputation is vital for deliverability. If you are using a different 'from' domain, you should ensure the new domain is properly authenticated and follows the same best practices to protect your sender reputation.

Email marketer from Email on Acid shares that it is important to test your email authentication when using a different 'from' domain. Use tools to verify SPF, DKIM, and DMARC records to ensure your emails pass authentication checks and reach the inbox.

Email marketer from Mailjet shares that proper email authentication protocols like SPF, DKIM, and DMARC are crucial when using different 'from' domains to avoid being flagged as spoofing. Failing to implement these can significantly harm email deliverability.

Email marketer from Litmus shares that using a different 'from' domain can trigger spam filters if the email content and authentication are inconsistent. It's crucial to align the 'from' domain with your brand and ensure proper authentication protocols are in place.

Expert from Email Geeks explains that 'mailed by' would be the return-path (bounce)/SPF domain, that is probably okay that they don’t match, as long as they’re both in the same domain. For DKIM, if you’re signing as bitly.com, but using a from address of accounts.bitly.com, that’s not horrible if they’re both part of bitly.com, but suggests correcting the DKIM signing settings to sign as accounts.bitly.com instead. In general you want the signed-by domain to exactly match your from domain, whenever possible.

Expert from Word to the Wise explains that using different 'from' domains without proper authentication will impact your domain's reputation and that could result in it being seen as spoofing.

Expert from Email Geeks explains that it is theoretically fine to send from two places using that subdomain, and if you have full control over the DNS, you can fully implement DKIM auth for both sending platforms, referencing how clients at Salesforce would send from both Marketing Cloud and some transactional message system, as the same domain or subdomain, successfully.

Documentation from RFC explains the technical specifications of SPF, emphasizing that the 'from' domain must be properly authenticated to prevent email spoofing. Implementing SPF records is essential to verify the sender's legitimacy and ensure deliverability.

Documentation from DMARC.org explains that implementing DMARC policies is essential for preventing email spoofing and phishing attacks. Using different 'from' domains can be a security risk if not properly authenticated with DMARC, SPF, and DKIM.

Documentation from Google explains that Sender Policy Framework (SPF) records help prevent email spoofing by verifying that emails are sent from authorized mail servers. Without proper SPF configuration, using a different 'from' domain may lead to deliverability issues and being marked as spam.

Documentation from Microsoft responds by stating that organizations should implement DMARC policies to protect their domains from email spoofing. When using a different 'from' domain, DMARC can validate whether the email is legitimate and prevent malicious actors from impersonating your brand.
