This free tier is genuinely usable and does not require a credit card, but it is tightly capped: 3 inboxes, 3,000 emails a month, 3 GB of storage, and only a small amount of team and webhook capacity. Compared with the $20 Developer plan, it offers roughly a third of the practical entry-level capability, so a fair monthly value is about $2.

  • Includes 3,000 emails per month.
  • Provides 3 GB of storage.
