About

Up to 5 million outgoing emails per hour. 99.8% of your emails will arrive at their destination. Feel like you might need a dedicated IP? Let us know and we’ll provide one, while also keeping an eye on the performance and stability of our shared IP pools. Get started with Web API or SMTP in minutes. GDPR compliant. No sensitive data to upload, just make a request to send an email and get the statistics back. UniOne has no personal information stored on our servers. Check your email statistics, keep an eye on delivery rates, openings, click-throughs, and unsubscriptions to manage your contacts more effectively. If you find your results are low, UniOne will make a few recommendations as to how to fix this. Running out? The system will let you know when your monthly plan is going to expire. You can also add multiple notification addresses so your IT team will be updated with recent reports or invite your teammates as shared access members to manage the account together.

About

SendBunny is an AWS-native, self-hosted email platform for startups, developers, SaaS teams, and businesses that want more control over their email infrastructure. It deploys into the customer’s own AWS account and uses Amazon SES for delivery. SendBunny combines transactional email APIs, marketing campaigns, unlimited contacts, templates, analytics, suppression management, multiple sending domains, a team inbox, and MCP support for AI workflows in one platform. Unlike other email providers that charge recurring fees based on contacts or usage tiers, SendBunny is available for a $199 one-time license. Customer data and application infrastructure remain inside the user’s AWS account. SendBunny is designed for teams looking for an alternative to Resend, SendGrid, Mailgun, Mailchimp, and similar email platforms without giving up ownership of their infrastructure or building the full email layer around Amazon SES themselves.

Pros & Cons from Real Users

Pros

  • One time fee, no vendor lock in and a full email platform with API & MCP. The experience from product to onboarding was smooth. Works great if you already have AWS production access or in the SES ecosystem already.

Cons

  • Must get AWS production access to use the product. Works great if you are already in SES.
