Where each one falls short

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

Bluemail

Its AI features are minimal next to Spark or Canary, so users specifically wanting AI drafting or summaries will find it thin.
The interface exposes a large number of settings and toggles, which makes initial setup slower than more opinionated clients.
Business pricing is not published, so an organisation has to go through a sales conversation to learn total cost.
Free-tier support is largely community forum and help articles rather than direct responsive support.
Some optional cloud features, such as certain sync and backup functions, have historically required a paid add-on despite the base app being free.

BoldSign

Premium plan: additional envelopes cost $0.50 each after 250/month limit
Monthly billing costs 60-85% more than yearly billing (no 40% discount)
Enterprise API requires minimum $30/month
