The short version

  • Each has a real cost: Bloomreach the three products have separate origins, separate pricing units and separate onboarding, so a single bundled quote hides which parts you are actually committing to.; 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.
  • They diverge on capability: Bloomreach covers Engagement CDP, Sailthru covers Interest profiles.
  • 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.

Bloomreach

  • The three products have separate origins, separate pricing units and separate onboarding, so a single bundled quote hides which parts you are actually committing to.
  • Engagement is priced on tracked profiles, so a customer database that keeps every inactive account raises the bill whether or not those people are ever messaged.
  • The flexibility of the data model and Jinja templating needs technical ownership, and marketing teams without a developer typically use a fraction of the product they pay for.
  • Content is the least invested of the three lines and buyers evaluating it against dedicated headless CMS vendors usually find the gap widening.
  • Support and implementation quality vary between the Bratislava engineering base for Engagement and the US organisation, and escalation paths differ by product.

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.

Answered from the vendors’ own pages

Bloomreach: Is Engagement just Exponea renamed?

It is the Exponea product line, continued and extended after the 2021 acquisition, with its engineering still centred in Slovakia. Buying it standalone is common.

Sailthru: Who owns Sailthru now?

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

Bloomreach: Do we have to take Discovery to get Engagement?

No. They are sold and priced separately, and plenty of customers run Engagement alongside a different search vendor.

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.

Bloomreach: How is it priced?

Engagement by tracked profiles and event volume, Discovery by request volume. Neither is published, and both are annual commitments.

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.
