Best Transactional Email Software

Transactional email software refers to software that sends emails in response to pre-established actions taken by recipients. These products send email notifications in response to users’ actions; some examples include a welcome email after creating a new social media account, an email receipt from an e-commerce transaction, or an email for a new newsletter subscription. Businesses use these tools for automating personalized emails as transactions occur. Teams use transactional email software to track metrics such as emails sent, received, opened, and bounced. Transactional email tools are useful to for customer retention, sales, marketing, and public relation teams. Transactional email software integrates with additional types of software, such as CRM, email marketing, and e-commerce products, to maximize the benefits to your business.

To qualify for inclusion in the Transactional Email category, a product must:

  • Provide automated email response tools
  • Enable emails to be sent automatically as a result of action-based triggers
  • Send customized or personalized emails
  • Sync with business software such as e-commerce, social media, or other tools
  • Provide administration tools to track emails sent and received, as well as their results
