Pricing questions
Yes. Volume is identical across Starter, Business and Pro — you choose a plan based on the level of deliverability, retention, support and infrastructure you need, not on how many emails you send.
Each recipient message you send through SMTP or the API counts once toward your monthly volume.
Anytime. Move between Starter, Business and Pro, or change your volume tier as your sending grows.
We price those individually, often with dedicated infrastructure. Talk to us and we'll put together a custom quote.
