About Captain Data
Captain Data builds no-code data automation for sales and operations teams. Fifteen people work there. It finds its own customers through cold email, so outbound is part of how the company grows.
Before Mailpool
Captain Data automates other people’s work for a living. Its own email infrastructure was still being set up by hand, and the sales team was the one doing it. Every new sending domain took about 3 hours, which covered buying the domain, creating the inboxes, adding the DNS records and checking that they were right.
That work set the ceiling on outbound. Sending more meant more domains, and more domains meant more hours from people who were supposed to be selling. Deliverability was a problem too, and email that doesn’t reach the inbox costs customers, which is the whole point of sending it.
The move to Mailpool
Captain Data moved its domain and inbox setup to Mailpool. A new sending domain takes about 4 minutes instead of about 3 hours, and SPF, DKIM and DMARC are set automatically.
Guillaume Odier, Captain Data’s co-founder and CEO, says what surprised the team most was the simplicity. Setting up new domains in minutes freed them to go back to building the product.
Captain Data on Mailpool today
Captain Data runs 170 inboxes and counting, and sends about 60,000 emails a month from them.
Setting those up isn’t really a job any more. It runs programmatically, with Mailpool’s MCP server working alongside the MCP server of the sequencer the team sends from, so domains and inboxes get created, authenticated and handed to campaigns without a person in the middle. There is very little left to manage, and the sales team that used to spend hours on setup spends them selling instead.
The takeaway
For a small team, the real cost of setting up infrastructure by hand isn’t the hours. It’s who spends them. Every domain your sales team configures is time they didn’t spend talking to prospects, and that trade gets worse the more you send.
If your reps are buying domains and pasting DNS records, that’s the first job to hand over. Software is better at it, and they have something better to do.
