Send Fee Floor

Send Fee Floor is the list size at which a client's platform subscription is too small to carry a retainer on its own. A 5,000-contact account on EmailOctopus or Moosend can run under $50 a month, so a $1,500 monthly retainer cannot be justified by sending alone. Agencies clear the floor by bundling list growth, segmentation, creative, and lifecycle flows into one scope, then pricing the bundle against outcomes rather than send volume. The floor moves with the client: a 40,000-contact ecommerce account on Drip or Klaviyo-class tooling supports more service hours than a 2,000-contact service business on AWeber. Zapier's September 2026 comparison of Kit and Mailchimp notes that picking a platform mismatched to a client's growth stage forces a disruptive mid-campaign migration, which is the moment the floor gets tested hardest.
