What is email marketing software?
Email marketing software helps brands write, send, and track email campaigns at scale. Most tools focus on sending infrastructure (ESPs). Milgo focuses on the hardest part: writing emails that open and convert — then handing them to your existing ESP.
Why Milgo over Klaviyo or Mailchimp?
Klaviyo and Mailchimp are sending platforms. Milgo is the copy + deliverability layer that makes those sends actually perform. You can keep your ESP and bolt Milgo on top — no migration, no risk.
