Best Email Marketing Software for Agencies
Agency teams need something different from solo creators or in-house marketers. The best email marketing software for agencies combines client separation, reusable templates, reporting, and enough flexibility to manage multiple accounts without turning operations into a mess.
What We Looked For
We focused on multi-client management capabilities: sub-accounts, white-labeling, client reporting, role-based access, and agency pricing (per-client vs. flat fee). API quality and integration breadth were also critical since agencies need to connect many tools.

Frequently Asked Questions
Should agencies use one platform for all clients or let each client choose? +
Using one platform simplifies management, reporting, and training. Most agency-focused plans offer sub-accounts with separate billing. However, some clients may have existing tools they want to keep — flexibility matters.
Do any email platforms offer white-label options for agencies? +
Yes. ActiveCampaign, Brevo, and some enterprise plans allow white-labeling — you can present the platform under your own brand. This is valuable for agencies that want to offer email as a managed service.
What reporting features do agencies need? +
Look for cross-client dashboards, exportable reports, custom branding on reports, and performance benchmarking. The ability to share read-only dashboards with clients saves time compared to manually creating reports each month.
