Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

HEY

  • There is no free tier and no monthly billing option, so trying it beyond the trial means committing to a full year upfront.
  • Adopting HEY means changing your actual email address, not just installing a new client, which is a bigger migration than switching apps on an existing address.
  • The Screener and categorisation model is a real departure from a standard inbox, and some users take time to adjust or find it gets in the way for high volume mail.
  • Short vanity addresses carry steep additional annual fees, up to 999 US dollars a year for a two character address.
  • It does not connect to or manage existing Gmail, Outlook or iCloud accounts, so it cannot be used as a general client the way Mimestream or Apple Mail can.

Memberstack

  • Basic and Professional tiers include transaction fees of 4% and 2% respectively
  • Annual billing required for discounts; monthly pricing is higher
  • Webflow community builders receive Basic plan free but locked to that tier
