Why people consider alternatives to Smails

Smails is a native desktop app for Mac and Windows that keeps multiple Gmail and Outlook accounts in one window. Each runs in its own isolated session showing the real Gmail or Outlook web interface, so labels, filters, search operators…

Teams most often switch away when one of these starts to bite:

Pricing at scale as usage or premium tiers add up.
Missing integrations with the rest of your stack.
Performance or scale limits as your needs grow.
A specific feature gap you have hit in email clients.

The 7 alternatives below cover the same core job (email clients) with different trade-offs.
