With Mailbox, we’ll receive, store, and forward your messages so they’re ready when you are.
API Connect
Connect your existing forms to Mailbox with a simple POST call.
We can serve as a simple backup, or we can process the messages to help your team with convenient filtering and organization.

"Free" from a big company means you're paying with your data — or in this case, your customers' data.
We don't like that trade-off, especially when customers could be contacting us with billing issues, order concerns, or other private information.
We're firm on our privacy stance: "your data is yours". We don't look at it, we don't scan it, we don't share it, we don't train AI with it.
Simple: Forms take less effort. Even for the people who are willing to send an email, you still need someone on your side to receive and redirect or respond to it. It's easy for messages to get lost in the shuffle.
Having a shared inbox for "first contact" messages ensures that nothing gets lost or overlooked. When your whole team has access, they can proactively delegate, and these critical messages won't get buried in the avalanche of clutter in your email.
We had a form, too — lots of forms, actually. Then we got an email saying "Hey, are you still in business? Why I haven't heard back yet."
When our provider was acquired, they quietly changed their API limits and we lost months of inquiries. It went unnoticed because we were still getting our other emails.
We created FormBolt so we will have a fail-safe backup; Even if a provider goes down, our pipeline is protected.
We built FormBolt to fill our own needs, so development will happen either way.
The $9/month 'base platform fee' is enough to cover our hosting costs for most small teams, so regardless of how many messages you receive each month, the first 300 are free.
If you start getting a lot of traffic, we have low, tiered rates and generous discounts for higher utilization.
We don't have hard limits. Whether you receive 10 messages or 10,000, our rates are simple and fair, so there won't be big any surprises.
You can check your usage at any time, or estimate your bill using the calculator above.
Need higher utilization? We offer custom redundancy, SSO, and dedicated support for large-scale deployments. Contact Sales
