Publish Consistent Newsletters Without the Grind

AI curates content, writes summaries, and personalizes sections for each subscriber segment. Your editors review before every send.


Why this matters

Creating quality newsletters is one of the most time-intensive marketing tasks. Writers spend hours finding relevant content, writing summaries, and formatting — often resulting in inconsistent publishing schedules and missed deadlines. When newsletters ship late or skip weeks, subscriber engagement drops and unsubscribe rates climb.


How MultiMail solves this

MultiMail's AI agent scans your content sources, selects the most relevant articles, writes engaging summaries, and personalizes sections based on subscriber interests. With gated_send oversight, your editorial team reviews every newsletter before it reaches subscribers, maintaining brand voice and quality standards.

1

Configure Content Sources

Define your content sources — RSS feeds, blog posts, industry news, internal updates. The AI agent monitors these sources continuously and identifies the most relevant and engaging content.

2

AI Curates and Writes

The agent selects top stories, writes concise summaries, and organizes content into sections. It personalizes content selection based on subscriber segment interests and past engagement.

3

Draft the Newsletter

Using send_email, the agent composes the full newsletter with formatted sections, links, and calls to action tailored to your brand guidelines and subscriber preferences.

4

Editorial Review

With gated_send oversight, the composed newsletter enters the approval queue. Editors review for quality, tone, accuracy, and brand alignment before approving for delivery.

5

Send and Analyze

Approved newsletters are delivered to your subscriber list. The agent tracks engagement to refine future content selection and personalization strategies.

Common questions

Can the AI maintain our brand voice?
You provide brand guidelines, tone examples, and past newsletters as training context for your AI agent. The agent learns your style over time. With gated_send, editors can refine any sections that don't match your voice before sending, and these edits improve future drafts.
How does personalization work across subscriber segments?
Use MultiMail's contact tagging to segment subscribers by interest, role, or engagement level. The AI agent selects and prioritizes content differently for each segment. You can create separate newsletter editions or customize individual sections within a single template.
Does this handle unsubscribe compliance?
MultiMail automatically includes unsubscribe links and honors unsubscribe requests as required by CAN-SPAM and GDPR. Your AI agent can also track engagement signals to proactively remove disengaged subscribers before they report spam.
Can we A/B test subject lines?
Yes. Your AI agent can draft multiple subject line variants and use MultiMail's API to send different versions to test segments. Track open rates through the API to determine winners before sending to your full list.
