Modular Mail
What Modular Mail is
Modular Mail is a web-based email content management system for building campaigns inside templates with editable fields and locked structure. Teams can rearrange modules, edit text and image fields, and preview campaigns on desktop and mobile. Its drag-and-drop editor supports reusable content blocks, custom code editing, and custom fonts. AI Copy Assistant generates or refines text, while AI Alt Text creates accessible image descriptions; both follow configured brand voice and restricted-term rules. Finished campaigns export as production-ready HTML for upload to an existing email service provider, because Modular Mail is not an email sending platform. Listed integrations include Mailchimp, HubSpot, Salesforce, Klaviyo, Constant Contact, ActiveCampaign, Marketo, Braze, SendGrid, Campaign Monitor, Pardot, Iterable, Bloomreach, Customer.io, Mailgun, iHotelier, and other HTML-email platforms. Templates can be configured by Modular Mail, an agency, or your developer; custom builds are quoted by complexity. Plans start at £59 a month for Studio, with one seat and a 14-day trial. Business costs 349.00 GBP monthly, while Enterprise pricing is tailored.
