Top Email Marketing & Automation Companies

Email marketing and automation agencies own the inbox channel for a brand: the welcome, abandoned-cart, post-purchase and win-back flows that run on triggers, the campaign calendar that goes out on a schedule, and the platform underneath, whether Klaviyo, HubSpot or Braze. Online stores hire them to turn a list into repeat revenue, B2B teams to nurture leads between sales touches, and SaaS companies for onboarding and renewal sequences, usually after a migration, flat revenue from a growing list, or mail landing in spam.

Shortlist by the platform each agency is certified on and by what it reports: revenue per flow and per send, not open rates. Check whether copy and design are in-house and who owns deliverability.
