The short version

  • Each has a real cost: Customer.io essentials plan caps at 5,000 profiles (people and objects) and 1,000,000 monthly emails, with overages billed at $0.12 per 1,000 emails beyond that; Zoho Marketing Automation pricing is by contact count, so an inactive or unengaged list costs the same as an active one, and nobody in the business has an incentive to prune it until the next tier boundary arrives.

Where each one falls short

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

Customer.io

  • Essentials plan caps at 5,000 profiles (people and objects) and 1,000,000 monthly emails, with overages billed at $0.12 per 1,000 emails beyond that
  • Standard and Premium tiers show custom pricing only, and Enterprise is negotiated rate, so three of the four published tiers require a sales conversation
  • Monthly plans accept credit card only; annual billing via invoice (ACH/wire) requires the annual commitment

Zoho Marketing Automation

  • Pricing is by contact count, so an inactive or unengaged list costs the same as an active one, and nobody in the business has an incentive to prune it until the next tier boundary arrives.
  • The Enterprise plan caps users at 25, which is a hard ceiling for larger marketing organisations rather than an upgrade path.
  • Its value depends heavily on running Zoho CRM; used alongside Salesforce or HubSpot the integration is shallower and much of the scoring and attribution advantage disappears.
  • Zoho sells Campaigns, Marketing Automation and MarketingPlus as separate products with overlapping function, and buyers regularly purchase the wrong one and then migrate lists between them.
  • Support and deliverability tooling are basic next to dedicated senders, so sender reputation problems on a large list get less expert help than a specialist provider would give.
