Best email marketing platforms for agencies

Agency requirements barely overlap with everyone else on this site. You need multiple client accounts without multiple logins, enough user seats to put a team on them, reporting a client will accept and branding that is yours rather than the vendor’s.

Very few providers price for this well. The ones that do tend to charge for it explicitly; the ones that do not leave you running several separate subscriptions and reconciling them by hand.

What we weighted

Stated up front so you can disagree with the criteria rather than only with the conclusion.
  • Multi-client or sub-account management
  • User seats included before the per-seat charges start
  • White labelling and client-ready reporting
  • Whether a formal agency or partner programme exists
  • Total cost across several mid-sized client lists rather than one

Ranked by cost

25,000 subscribers approximates several client lists on one account. Automation, landing pages and forms are required because those are the three deliverables agencies are actually asked for.

Ranked by the effective monthly cost on your chosen billing cycle, converted to pounds where a provider quotes in another currency. Only the cheapest qualifying plan per provider is shown. Prices are the provider’s own published rate. Always confirm before buying.

Ruled out, and why

These providers have no plan that fits. Relaxing one requirement may bring them back.

  1. 1.GetResponse

    #4 on price for this preset

    The widest feature set for client work (landing pages, funnels, webinars and courses) so more client work can be done inside one subscription.

  2. 2.ActiveCampaign

    #9 on price for this preset

    The automation depth that justifies retainer work, plus a mature partner programme.

  3. 3.Brevo

    #3 on price for this preset

    Send-based pricing suits agencies holding large client lists that are mailed to campaign schedules rather than continuously.

  4. 4.HubSpot

    Does not meet this preset’s requirements

    Only when the client relationship is genuinely CRM-led. As an email tool it is the most expensive option on this site.

Who this page is not for

A freelancer running two or three small client lists does not need any of this. Separate cheap accounts per client are simpler to bill and easier to hand over.
