What the email infrastructure manages for you

Verification before sending

Every address is verified before the first email. Fewer bounces means a sender reputation that stays intact.

Warm-up and rotation

Mailboxes ramp up volume gradually and sends are spread across several domains and addresses, the way a human team would do it.

Reputation monitoring

Bounce rates, complaints, inbox placement: the health of every domain is monitored continuously, with alerts if it drifts.

How deliverability is protected, step by step

Properly configured secondary domains

Prospecting goes out from dedicated domains, separate from your main domain, with SPF, DKIM and DMARC configured from the start. Your brand stays protected.

A gradual, automatic warm-up

Each new mailbox ramps up volume over several weeks, with exchanges that build its reputation with mail providers before the first campaign.

Sends that are spread out and capped

Volumes are spread across mailboxes and capped per day, with natural sending rhythms. No mailbox exceeds the thresholds that trigger the filters.

Monitoring that acts, not just observes

If a domain's reputation deteriorates, the agent slows the sends, switches to healthy mailboxes and alerts you. The problem is contained before it costs you campaigns.

For teams that have burned their domain: start clean again

It's a classic scenario: months of mass sends from the main domain, open rates that collapse, then the discovery that the whole company's emails, including quotes and invoices, are landing in spam.

Prosperian's email infrastructure starts again on healthy foundations: fresh secondary domains, full warm-up, controlled volumes. Your main domain is kept out of prospecting and gradually recovers its reputation, while your campaigns resume on a dedicated infrastructure.

For scaling up: going from 50 to 500 emails a day without breakage

Multiplying your send volume by ten is not a matter of pressing the same button harder. Without rotation or gradual ramp-up, spam filters read the change in behavior as a warning sign and deliverability collapses at the worst moment, right in the middle of a sales push.

Prosperian's infrastructure absorbs the load increase: additional mailboxes are created and warmed up in advance, volumes are spread out and caps are respected. You increase the pace without your inbox placement rates moving.

For leaders: protect the company domain

Your company domain is an asset: it carries your client exchanges, your contracts, your billing. Exposing it to mass prospecting means risking that all of the company's communication ends up in the junk folder.

By isolating prospecting on dedicated domains that are properly authenticated and monitored, Prosperian's email infrastructure eliminates this risk structurally. Whatever happens to the campaigns, the main domain and the company's reputation stay intact.

Frequently asked questions about email infrastructure

Why use secondary domains for prospecting?

Because high-volume prospecting always carries a risk to sender reputation. By isolating it on dedicated domains, your main domain, the one that carries your client exchanges and your billing, stays out of reach of spam filters, whatever happens to the campaigns.

How long does a mailbox warm-up take?

Expect two to four weeks for a new mailbox to reach its cruising volume. The ramp-up is gradual and automatic: the mailbox first exchanges at low volume to build its reputation, then increases the pace in steps. Mailboxes are prepared in advance so they don't delay your campaigns.

How many emails can a mailbox send per day?

The caps are deliberately conservative, usually a few dozen emails per mailbox per day. Overall volume comes from multiplying mailboxes and from rotation, not from overloading a single address. That is what keeps placement rates high over time.

What happens if a domain's reputation drops?

Monitoring detects the drift (rising bounces, spam placement, complaints) and the agent reacts immediately: slowing the sends, switching traffic to healthy mailboxes, an alert in your workspace. The affected domain is rested until its reputation recovers.

Who manages the SPF, DKIM and DMARC configuration?

Prosperian. These authentication protocols are configured when the prospecting domains are set up, then checked continuously. You have no DNS work to do yourself, and your technical team does not need to step in.
