Emails sent from Salesforce are being marked as Spam or Junk mail

Date de publication: Feb 23, 2026
Description

From time to time emails sent from Salesforce could end up quarantined in the recipients MUA or MTA.  This could be for a variety of reasons ranging from email content looking like spam content to Salesforce MTAs being blocked by mail filters and spam services on the internet for no valid reason.  To ensure the highest deliverability of your emails see some of the recommendations and tips below. 

Résolution
  1. Ensure that Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting, and Conformance (DMARC) are properly configured for your email domain. Note that recent changes by ESPs (Email Service Providers) require that sent email passes all 3 off the above for delivery if emails are detected as being "bulk sends" on the internet (5000 and above emails per day).  
  2. Salesforce supports and recommends these standard email security protocols. If your email domain has a DMARC policy, confirm that either SPF or DKIM not only passes but also aligns with your domain, as defined by DMARC.  Incorrect DKIM alignment can occur if the Domain field in the DKIM Key does not match the domain in the “From header”.
  3. Monitor your email reputation by proactively removing bad email addresses and utilizing the Bounce Management feature to flag invalid addresses on Contact, Lead, and Person Accounts.  This can be assisted by including the IsBounce field in Reports and List views.
