Email drafting, inbox triage, reply generation. Ranked by quality, cost, and real-world performance.
4 models compared · Data powered by Artificial Analysis
Ranked comparison of 4 AI models for email tasks. Gemini 3 Flash leads on quality (score 42), while Gemini 3 Flash provides the most affordable entry point.
Email processing — drafting, triaging, and replying — is one of the most cost-effective uses of AI. Since individual emails are short, even budget and free models can handle this well.
The key metric for email tasks is speed (tokens per second) rather than raw quality. A fast model that delivers "good enough" responses will serve you better than a slow frontier model for this use case.
Most users can run their email agent entirely on free or budget-tier models, keeping monthly costs under $1 for moderate volume.
