AI marketing platforms for email campaigns, lead nurturing, audience segmentation, and content distribution.
Best if your CRM is HubSpot.
Free tier · Starter £15/mo
HubSpot Marketing Hub is the obvious answer if your CRM is also HubSpot. AI features (Breeze) sit across the platform: content drafting, list segmentation, send-time optimisation. Less work to integrate than running ActiveCampaign separately.
Stronger automation logic; better if you don't have HubSpot.
From £12/mo
ActiveCampaign's automation builder is more powerful than HubSpot's at the entry tier. Right pick if you want serious marketing automation without committing to the HubSpot ecosystem. AI features are stable and useful.
Most accessible free tier in the category.
Free tier · Essentials from £10/mo
Mailchimp's free tier handles up to 500 contacts and basic AI content drafting. Easiest entry point for teams just starting with email marketing.
Best for eCommerce specifically. Deeper AI segmentation and predictive analytics than HubSpot for shop-driven businesses.
