Frequently Asked Questions
What is Aigeon and what does it do?
Aigeon is an AI-native email operating system built for publishers, newsletter creators, and media companies. It was created by the team that built NewsBreak's email infrastructure, which processes over 1 billion emails per month. The platform lets publishers send unlimited emails to unlimited subscribers at no monthly cost by embedding programmatic ads in each email. Its Flow AI feature automates campaign building by converting plain English instructions into sequences, segmentation rules, and conditional sends.
How much does Aigeon cost?
Aigeon's ad-supported tier is free with no subscriber limits, no send caps, and no monthly fee. Instead, publishers earn $0.50 RPM per 1,000 email opens through three programmatic ads embedded in each email. The ad-free option costs $3 to $5 per 10,000 sends for publishers who want clean emails without embedded ads. An enterprise tier with custom pricing is available for teams needing full API access, dedicated support, and custom send limits. There are no per-subscriber charges on any tier.
What are the main features of Aigeon?
Aigeon's primary features include Flow AI (a conversational assistant that builds automation sequences from plain English), a built-in programmatic ad network that pays publishers per open, Dynamic Content Blocks that pull live content from external feeds into emails automatically, and enterprise-grade deliverability at 99% delivery rate with 2,000 emails per second capacity. The platform also includes a 50M+ subscriber partner growth network for audience acquisition and full SPF, DKIM, and DMARC domain verification support.
Is Aigeon free to use?
Yes, Aigeon is free on its ad-supported tier with no subscriber cap and no send limit. The trade-off is that three programmatic ads are embedded in every email, and Aigeon pays the publisher $0.50 per 1,000 opens from those ads. Publishers who want to send without ads pay $3 to $5 per 10,000 sends instead. Setup takes under 5 minutes and includes CSV import and Mailchimp migration tools.
What are the best alternatives to Aigeon?
The closest alternatives to Aigeon are beehiiv, ConvertKit (now Kit), and Mailchimp. Beehiiv is worth considering when you need native paid subscriptions and a built-in recommendation network, as its paid plan starts at $39/month with stronger creator monetization tools. ConvertKit is a better fit for individual creators and course sellers who need tag-based automation without programmatic ads. Mailchimp suits teams already integrated into the broader Intuit ecosystem. None of these pay publishers per send like Aigeon's ad model does.
Who is Aigeon best for?
Aigeon is best for high-volume newsletter publishers, digital media companies, and vertical content publishers who currently pay several hundred dollars per month on traditional ESPs and want to eliminate that cost. Named customers include NewsBreak, OK Magazine, SportsNaut, and Law & Crime. It is less suitable for B2B SaaS marketing teams that need CRM integrations, lead scoring, or branded transactional emails without third-party ad content appearing alongside their communications.
Does Aigeon have an API?
Aigeon provides API access for list import and migration on all tiers, allowing publishers to move subscribers programmatically. Full API access with custom limits is available on the enterprise tier, which requires contacting the sales team for pricing. The platform also has a public GitHub presence at github.com/aigeon-ai with several MCP server tools. Detailed developer documentation is not publicly listed on the main website, so teams needing deep API integration should confirm scope before committing to the platform.
