# HTML download and portability

*@hubspot_hater | B2B SaaS | 2 years ago*

Context: B2B SaaS team, 400k monthly sends. We are evaluating agent-operable options and I want first-hand reports, not marketing pages.

Specifically interested in design generation and deliverability.

  **lifecycle_lena** (116 votes): Have you capped daily sends? We hit a loop once and reputation dipped.
