The short version

  • Each has a real cost: Iterable no pricing information published on their site - contact sales required; Sailthru the product sits in a portfolio with several overlapping platforms under one owner, so roadmap investment is a portfolio decision rather than a product decision and is worth asking about in writing.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Iterable

  • no pricing information published on their site - contact sales required

Sailthru

  • The product sits in a portfolio with several overlapping platforms under one owner, so roadmap investment is a portfolio decision rather than a product decision and is worth asking about in writing.
  • Pricing counts stored profiles, so retained inactive readers keep costing money long after they stopped opening anything.
  • On-site personalisation requires a developer to implement the JavaScript and maintain the content feed, which puts the highest-value feature behind engineering time.
  • Zephyr is a proprietary templating language, so template maintenance skills are scarce compared with the Liquid syntax used by most competitors.
  • It is built for high-cadence content and retail sending, and B2B lifecycle programmes with long sales cycles sit poorly on the model.

Sailthru: Who owns Sailthru now?

Marigold, formerly CM Group, which also owns Campaign Monitor, Emma, Selligent, Liveclicker and Cheetah Digital.

Sailthru: Does that affect the roadmap?

It can. Overlapping products in one portfolio compete for investment, so ask which platform is the strategic one for your segment before signing multi-year.

Sailthru: Is it worth it just for newsletters?

For personalised daily newsletters at publisher scale it remains one of the strongest options. For simple broadcast sending it is heavily over-specified.
