1) Enterprise procurement or regulated industries requiring formal security attestations
If procurement requires SOC 2 Type II, ISO 27001, or a detailed security whitepaper and DPA terms, Saay’s public documentation appears insufficiently detailed for standard enterprise procurement checklists.
2) If robust marketing automation and attribution are required
Ecommerce-focused platforms (e.g., Postscript) typically provide more advanced cart abandonment flows, lifecycle automations, and revenue attribution.
3) If operating in restricted or high-risk verticals
Saay’s content restrictions explicitly limit or forbid categories such as cannabis (in the US), certain finance and lending messages, and gambling promotions. Operating in these verticals carries a higher risk of account restriction or carrier blocking.
4) If billing or cancellation certainty is critical
Although Saay publishes cancellation and refund terms, at least one public complaint alleges billing and account closure friction. Buyers requiring strong billing guarantees should validate cancellation behavior during a pilot with controlled spend.
5) If guaranteed throughput windows are required for time-sensitive campaigns
Saay indicates sends can take from about 20 minutes to a few hours depending on conditions, and daily allotments can limit bursts. Buyers that require guaranteed throughput SLAs should consider larger providers or CPaaS vendors with documented SLAs.
