Turn your email database into revenue. With zero risk.
You spent years building your list. It is one of the most valuable assets you own, and right now it may be earning a fraction of what it could. Fortitude Send runs the whole thing for you, and on revenue share there is nothing to pay upfront.
A big list is valuable, fragile, and easy to waste.
Dormant lists decay
Addresses go stale, complaints creep up, and what was a goldmine quietly turns into a hazard.
One blast can burn it
A single rushed send into a cold audience can take a domain down for months, and there is no easy way back.
Doing it properly is a job
Provisioning domains, warming them, balancing providers and protecting reputation is a full-time discipline, not a tool.
We only earn when your list earns.
We plug into your list, run everything end to end and take an agreed share of the revenue we generate. No licence fee, no setup bill, no monthly minimum. If your list doesn't earn, neither do we. For a dormant database, that is found money.
- No upfront cost and no monthly minimum.
- Incentives fully aligned with your results.
- Prefer a fixed fee? Licensing is available too.
What we handle
- Domain provisioning, warm-up and sending infrastructure
- AI campaign creation, copy and original imagery
- List verification and continuous suppression
- Deliverability monitoring and reputation protection
Built so your list earns more without earning less trust.
Verify first
Lists are validated and re-verified continuously so risky addresses never reach a send.
Warm and ramp
Fresh domains are warmed with real engagement and volume is ramped carefully, never blasted.
Guard continuously
The Reputation Guardian throttles or pauses on its own before a single signal can spread.
Frequently asked questions
Can I monetise a dormant email list?
Yes, that is the use case we built this for. We verify the list, warm fresh sending domains, ramp engagement carefully and build campaigns designed to wake the audience back up. On revenue share, there is nothing to spend to find out what it can earn.
What does revenue share cost upfront?
Nothing. There is no licence fee and no setup bill. We take an agreed share of the revenue we generate. If your list does not earn, neither do we.
Who owns the data and the relationship?
You do. Your list, your subscribers, your relationship. We operate the sending on your behalf inside an isolated workspace, and your data is never shared or co-mingled with anyone else's.
Will sending to an old list hurt my reputation?
Not the way we send it. Lists are verified and suppressed first, fresh domains are warmed before they take volume, and the Reputation Guardian throttles or pauses on its own if signals turn. The whole point of the platform is to protect the asset while it earns.
What kind of lists do you work with?
First-party email databases of meaningful size, typically 100,000 contacts and up. The system is built for lists in the millions, but it works well for anyone who has a serious audience they aren't mailing properly yet.
