What are the best alternatives to Omnisend?
The main alternatives to Omnisend covered here are Klaviyo, Mailchimp, Brevo and ActiveCampaign. Klaviyo may suit online stores that want ecommerce-driven email and SMS flows, while Mailchimp may suit small businesses that want a well-known all-round email tool. None is best for everyone: the right email marketing platform depends on team size, budget and which Omnisend limitation you are trying to solve.
Teams usually start looking beyond Omnisend for documented reasons: billable contacts include non-subscribers, such as customers who ordered without opting in; SMS now requires Pro for new paid subscriptions. Omnisend remains a reasonable fit for online stores that want email and push, with SMS on Pro, so an alternative is not automatically better, only different.
Below, every option is compared with Omnisend in one table, then described with its strengths, trade-offs and pricing, each taken from its own sourced profile. Anything the sources do not document is marked as unknown.
