User experience: We assessed the intuitiveness of the dashboards, the clarity of reporting, ease of setup, and the overall workflow for day-to-day management.
Support: We looked into the availability and quality of customer support, including documentation, email, chat, and dedicated account management, where applicable.
Pricing structure: We analyzed the transparency and flexibility of pricing models, noting free tiers, domain limits, email volume caps, and any hidden costs or upselling tactics. We identified price as cheap, medium, or expensive based on entry-level paid plans and included features.
Community reputation: We factored in publicly available reviews and feedback to gauge user satisfaction and identify common pain points (or lack thereof).
