The agentic AI email platform for developers. Free for life.

Yes, for life. SendBunny Free costs nothing, has no contact or sending limit, and gets every update and bug fix at no cost: transactional email and the API, templates, the inbox, webhooks, contacts and lists, and AI agents through MCP. It runs in your own AWS account, so you pay Amazon about $0.10 per 1,000 emails and nothing to us. Campaigns, automations, forms, landing pages, segments, topics and smart inbox sorting are SendBunny Premium, $199 once, with an optional updates plan at $99 a year. Without the updates plan, your install stays on the version you buy. Upgrading keeps every contact, template, key and message.

No. You click one pre-filled button in the AWS console, “Create stack”, and the installer does the rest. Updates are a single click inside your app. You never touch a terminal or write configuration.

No. There are no servers to look after. sendbunny runs on Amazon's managed services inside your AWS account, so there is nothing to patch, scale or keep running. When a new version is out, you press Update and it installs itself in a few minutes, keeping your data and settings. It works like a subscription, without the monthly bill.

An AWS account with Amazon SES production access, and about ten minutes. New AWS accounts start in the SES sandbox, which only emails addresses you have verified; you ask Amazon for production access, and the app links you straight to the form. A sending domain you own is recommended, and the app walks you through connecting it. Not sure where you stand? Ask us in the form at the bottom of the homepage, or email support@sendbunny.co.

You pay AWS directly for what you use. Sending 10,000 emails costs about $1.20: $1.00 to Amazon SES ($0.10 per 1,000) and about $0.20 of serverless infrastructure to send them. Amazon also bills about $1.50 a month to keep it ready (stored keys and monitoring), even when you send nothing. There are no sendbunny fees on top. Since July 2026 Amazon starts new accounts on its Essentials plan at $0.16 per 1,000; the app shows which plan you are on and switches you to the standard $0.10 price in one click.

No. sendbunny installs alongside your existing infrastructure as its own stack, and a hard product rule says it never modifies, takes over, or deletes anything it didn't create. Where AWS has account-wide settings (like inbound email rules), it detects what exists and coexists additively. It never replaces your configuration.

New AWS accounts start in the SES sandbox, which only delivers to verified addresses. The app shows your sandbox status and deep-links to the official AWS form for production access. AWS mostly just wants your website URL, and approval is a routine review. Until then you can set everything up and send tests to verified addresses.

Yes. You can install SendBunny, set everything up and send tests to your own verified addresses. To email your list you need production access, and we help you ask for it: use the form at the bottom of the homepage, or email support@sendbunny.co.

Add your domain and the app generates the exact DNS records for authenticated sending: DKIM, SPF, and DMARC. If your DNS runs on Route 53 in the same account, one click applies them (skipping anything that would conflict with records you already have); otherwise copy them into your DNS provider. Status updates automatically once AWS verifies.

Yes. Pick your old tool, follow its export steps, and drop the files as they came: a ZIP, CSVs, an Excel workbook or JSON. Subscribers, unsubscribes, bounces, lists, tags and fields land where they belong. You check everything before it moves, anyone who said no stays a no, and moving in emails nobody. Large lists import in the background.

Yes. Sending runs through Amazon SES, the same infrastructure Amazon uses for its own email, and everything around it is serverless and scales automatically. 10 emails a month or 100 million, it is the same install with no plan to upgrade and no server to resize. As your volume grows, AWS raises your SES sending limits on request, a routine approval.

Yes. Sign-in is invite-only: an admin invites teammates and assigns admin or member roles. There is a shared team inbox the whole team can use, and every privileged change is recorded in an audit log.

Yes. Every install includes a REST API. Create a key in the dashboard (shown once, stored hashed, revocable anytime), then POST a from, to, subject, and body, or reference a stored template by alias and pass merge data. Suppression is enforced on this path too. From Node.js, our official SDK does it in a few lines: npm install sendbunny. Webhooks tell your app the moment an email is delivered, bounces, is opened or clicked, or someone unsubscribes.

Yes, and not just to send. Connect Claude Code, Claude Desktop, Codex, Cursor or VS Code over MCP: paste one URL, sign in, and choose Send mail, Inbox or Full access for each domain. The agent gets 182 tools covering everything in the dashboard, from campaigns and automations to segments, sign-up forms, landing pages, the inbox and settings. Every tool says whether it reads, changes or deletes, everything it does shows up in your dashboard at once, and you can disconnect it any time.

The fundamentals, on by default: authenticated sending with DKIM, SPF, and DMARC, RFC 8058 one-click unsubscribe on campaigns, automatic suppression of hard bounces and complaints, and a dashboard that tracks your bounce and complaint rates against AWS's thresholds so you see trouble early. Sending is paced to your Amazon daily limit, Gradual Send warms up a new domain, every marketing email carries your address and a way out, and readers can turn off one kind of email instead of unsubscribing from everything.

Because running a mail server was never the hard part. Reaching the inbox is, and that comes down to IP reputation. Gmail, Outlook, and Yahoo decide where your email lands largely from the sending IP's history, and cheap VPS addresses have been recycled through years of spam. Many sit on blocklists before you send a single email, so a $5 server feels free right up until every campaign lands in spam, unseen. Amazon SES is strict about who gets to send exactly so its IPs stay trusted, which is why your email actually arrives.

No. We never receive your credentials, and nothing in the product phones home with your data. During install and updates, the installer sends one-way progress notifications so your deploy page can show a status bar, and that's it. The install template is six readable CloudFormation resources you can audit before clicking.

No one can lock you out, as long as you follow the email best practices and don't spam. sendbunny runs in your own AWS account, and we can't log in or switch you off. Amazon SES also keeps track of bounces and complaints, as every email service does. Send only to people who asked to hear from you and keep your list clean. sendbunny helps: addresses that bounce or complain are never emailed again.

Only you. Your list lives in your own AWS account, and sendbunny never receives a copy, so we can't share, sell or rent it. Ever signed up somewhere, then got email from companies you'd never heard of? Addresses get passed along. With sendbunny, your subscribers' addresses stay with the business they trusted: you.

Your platform keeps running as if nothing happened. It lives entirely in your AWS account and never depends on sendbunny's servers to send, show your dashboard, or store your data. The only thing that would stop arriving is updates.

Premium keeps working, forever: the one-time purchase is a lifetime license. You just stop receiving one-click updates until you renew, and renewing later picks up right where you left off. SendBunny Free has no yearly fee and gets every update at no cost.

Nothing breaks. Updates deploy the backend first and swap the dashboard last, so if any earlier step fails, your current version stays live and campaigns that are mid-send keep sending.

It's the opposite of locked in: everything lives in DynamoDB tables and S3 buckets in your own AWS account. Export it with standard AWS tools whenever you like, or delete the whole stack and it's gone. We couldn't hold your data hostage if we wanted to.
