Core concepts
A quick tour of the building blocks in EmailFlow AI and how they fit together. Understanding these five ideas — templates, audience, campaigns, automations, and brand — makes everything else in the product click.
Templates and emails
An email is the design you send: its layout, copy, images, and HTML. You can create one from a plain-English prompt in the AI builder, start from the template gallery, or build it by hand. Your saved designs live in Templates and can be reused across campaigns and automations. Every email is responsive by default and previewed live as you edit.
Audience: lists, subscribers, and segments
Your contacts are organized into lists. Each contact is a subscriber with an email address and any custom fields you define (first name, company, plan, and so on). A segment is a saved filter over a list — for example, “subscribers in Japan who opened the last campaign” — that you can target instead of the whole list.
Campaigns vs. automations
A campaign is a one-time send: you pick an email, choose recipients, and send or schedule it. An automation is an ongoing flow that reacts to events — a new subscriber, a birthday, a tag being added — and sends the right message at the right time, on its own. Use campaigns for newsletters and announcements; use automations for welcome series, re-engagement, and lifecycle journeys.
Brand
Your brand profile stores your logo, colors, fonts, and tone of voice. The AI uses it to keep every email on-brand, and Brand Assets gives the AI real images to work with. You can build this profile automatically by scanning your website.
Sending and keys
EmailFlow AI uses a Bring Your Own Keys model. You connect your own sending server (Amazon SES, Mailgun, SendGrid, or any SMTP relay), your own AI provider (OpenRouter), and your own verification service. The platform imposes no per-email, per-token, or per-contact limits — you pay your vendors directly and control your costs. The only setup on the platform side is verifying your sending domain with DNS records. See Plans & quotas and AI credits & tokens for details.
