Groups.io stands out with our comprehensive suite of integrated collaboration tools that go far beyond basic email lists. Unlike Google Groups or other services, we offer a full calendar system for scheduling events, a robust file storage area, a wiki for documentation, integrated chat rooms, photo galleries, and even customizable databases. Our moderation tools are significantly more powerful, allowing fine-grained control over permissions and content. We also provide unique features like integrated polls, message hashtags for organization, and the ability to mute specific conversation threads. Perhaps most importantly, Groups.io delivers all this while remaining completely ad-free and respecting your privacy—we don't mine your data or show advertisements like many competitors do.

Groups.io scales effortlessly from small teams to massive communities. Our platform comfortably supports intimate groups of just 10 members all the way up to thriving communities with 100,000+ participants. There are no hard limits on group size with our paid plans. Free groups can have up to 100 members, while our Premium and Enterprise plans remove these limitations. Our infrastructure is designed for high-volume email delivery, ensuring reliable message distribution even for very large communities. Additionally, our moderation tools scale with your group size, providing the controls needed to manage communities of any size effectively.

No, Groups.io does not sell your data to advertisers or third parties. Unlike Google Groups or Facebook Groups, we have a strict privacy-first approach—your conversations are not mined for advertising data or used to build marketing profiles. We only collect the information necessary to provide our service, and we don't track your activities across the web. Our business model is subscription-based rather than advertising-based, which allows us to prioritize user privacy. Your email addresses and group content remain private and are not shared. You can review our complete privacy policy to see exactly what data we collect and how we use it, but the short answer is: we respect your privacy and don't monetize your personal information.

Yes, Groups.io offers a free Basic plan that includes essential mailing list features for communities with up to 100 members. For growing groups, our Premium plan at $20/month (or $220/year) removes the member limit and adds advanced features like subgroups, file storage, a photos section, a calendar, polls, member directories, and more. You can see full details of our pricing here.

Yes, our Enterprise plan includes custom domain support. With this feature, your group's website address will appear under your own domain name, and all email communications will be sent from your domain rather than groups.io. Additionally, your organization's logo will be prominently displayed on the website, replacing the Groups.io branding. This provides a seamless branded experience for your members and maintains your organization's professional identity throughout all interactions. The custom domain feature requires minimal technical setup, and our support team can assist with the configuration process.
