Send email and newsletters. Just ask.
Mailtea lets your AI assistant send and schedule email, check delivery, write and design newsletters, manage contacts, and build your publication's website, all from a conversation. It is for newsletter writers, creators and teams who send with Mailtea, and for developers who want an agent to handle email without writing integration code.

167 tools, grouped by what they work on:
| Tool family | What your assistant can do |
|---|---|
Email (email.*) | Send, batch, schedule, cancel and resend email, check it before sending, track delivery and engagement, and read and reply to inbound mail |
Newsletters (issue.*, monetize.*) | Draft, edit, preview, test, schedule and send newsletters, publish them to your website, follow delivery progress, and manage sponsor offers |
Templates (template.*) | Create, render, publish, duplicate and version reusable email templates |
Audience (contact.*, contact_property.*, segment.*, topic.*, suppression.*) | Manage contacts and their properties, import a CSV, build segments and topics, handle suppressions, and run referral milestones |
Automations (automation.*, automation_run.*, event.*, event_definition.*) | Build, validate, preview, enable and measure multi-step automations, and send the custom events that start them |
Website (site.*, section.*) | Edit pages, sections, navigation, footer, theme and design brief, manage images, and publish your publication's website |
Sending setup (domain.*, sender.*) | Add and verify sending and tracking domains, and manage senders |
Analytics (analytics.*) | Newsletter performance, trends, poll results and CSV exports |
Account (publication.*, api_key.*, webhook.*, auth.*) | List and create publications, connect custom website domains, manage API keys and webhooks, and check who is connected |
Your assistant picks the relevant skill from your request. You can also name a skill if you want to be explicit.
| Included skill | What it helps you do | Try saying |
|---|---|---|
Mailtea email (mailtea-email) | Send or schedule email, check delivery, draft newsletters, and manage contacts | “Help me send my first email.” |
Mailtea email design (mailtea-email-design) | Design welcome emails, newsletters, and reusable templates for real inboxes | “Draft a welcome email with one clear call to action. Do not send it yet.” |
Mailtea website design (mailtea-site-design) | Build or restyle your publication's website, with changes saved as drafts | “Draft an About page for my publication. Do not publish it yet.” |

The plugin does not replace Mailtea Studio, or the SDKs and CLI for application code. Use it when an AI assistant should do the work for you.
