Since ActiveCampaign offers great customer support and pricing, it’s the ideal Email Service Provider for very small businesses and entrepreneurs. ActiveCampaign offers benefits like free migrations, free online training, and a 2-year price lock, which ranges from $29/mo to $149/mo. Of course, they also have a trial option. We’d also recommend ActiveCampaign for clients in the retail and marketing sector (as opposed to eCommerce), as well as clients who want to integrate social media marketing.
