Where each one falls short

Gravity Forms

  • Basic license covers only 1 site and renews at $59/year after a discounted $44 first year
  • Pro license is capped at 3 sites; using it on more requires the Elite tier at $259/year renewal
  • Marketing integrations like HubSpot and Mailchimp are Basic-tier only, while payment and workflow add-ons (Stripe, Zapier, Trello) require Pro or above

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
