Pick Mails.ai if…
Mails.ai suits developers building AI agents that need to send and process transactional or conversational email. It is not for cold outreach, which the API refuses.
Pick Mixmax if…
Mixmax suits revenue teams that work in Gmail or Outlook and want email sequences, tracking, scheduling and CRM activity in one workflow. It is not suited to users of Apple Mail, Yahoo or other email providers.
