The short version

  • Only Postmark has a free tier, so it costs nothing to try first.
  • Each has a real cost: Postmark free tier caps at 100 emails per month with no overages allowed; Sitebulb desktop plans are limited to a single user, so teams need Sitebulb Cloud or paid add-on seats to collaborate.

Where each one falls short

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

Postmark

  • Free tier caps at 100 emails per month with no overages allowed
  • Basic plan ($15/mo) includes 10,000 emails then charges $1.80 per 1,000 extra; Pro and Platform tiers have their own lower per-1,000 overage rates ($1.30 and $1.20), so cost scales per email beyond the included volume
  • Custom high-volume pricing above the published tiers requires contacting sales

Sitebulb

  • Desktop plans are limited to a single user, so teams need Sitebulb Cloud or paid add-on seats to collaborate.
  • Large sites near or above the 500,000 URL Pro limit require reconfiguration or the Cloud tier to avoid hitting crawl caps.
  • Desktop crawling relies on local machine resources, so audit speed and scale depend on the user's hardware rather than cloud infrastructure.
