The short version

Only Brevo has a free tier, so it costs nothing to try first.
Each has a real cost: Brevo paid plans are priced by email volume sent per month, with higher tiers running past $100 per month as list and send volume grows; 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.

Where each one falls short

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

Brevo

Paid plans are priced by email volume sent per month, with higher tiers running past $100 per month as list and send volume grows

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.
