Best AI Email Writers for Iterable

Brew is an AI-native email service provider built to create and send on-brand email campaigns and automations with AI. It is described as “Lovable for email marketing,” helping teams build high-performing email programs in minutes without specialists, templates, or weeks of setup. Brew breaks down the email marketing workflow across strategy, copywriting, design, segmentation, analysis, sending, and automation, then rebuilds it with AI at the core. Its brand extraction captures fonts, colors, imagery, voice, and small design details, allowing it to generate emails that match the brand and render correctly across inboxes. Brew works through a chat-first interface backed by an AI agent that generates, edits, and sends emails, supporting newsletters, promos, welcome flows, abandoned-cart sequences, and transactional messages. Teams can use Brew as a complete ESP, generate emails and push them into platforms such as Klaviyo, HubSpot, or other ESPs.
