DELIVERABILITY

THE PROBLEM
Blasting your list looks like spam.
Hit send on your whole list at once and Gmail notices. So does Outlook. A sudden flood of mail from a domain that usually sends a trickle reads exactly like the pattern spam filters are built to catch, even when every word of your campaign is honest and every recipient asked to hear from you.
The damage doesn't end with that one campaign. One bad afternoon can sink a domain's reputation for weeks, pushing your next email into spam folders right alongside the one that tripped the alarm. For a small business sending a handful of campaigns a month, one mistimed blast can undo months of careful list-building.
Mailer Moose removes the blast entirely. Every campaign leaves at a pace inbox providers already trust, so there's nothing sudden for a filter to flag.

HOW IT WORKS
From send button to inbox, paced the whole way.
Here's what happens behind the scenes the moment you hit send.
You hit send
Your campaign queues up, ready to go out to everyone on your list.
We check the room
Each inbox provider's current response sets its own sending rate for this campaign, adjusted from how it's behaving right now.
Mail goes out across your domains
Your campaign is spread across your sending domains, with every recipient's message fully aligned to the one domain carrying it.
Pace holds, no matter what
If a provider asks us to slow down, the campaign takes a little longer. It never bursts to catch up.
IN DETAIL
Pacing, taken apart.
Three things happen under the hood of every campaign you send.
PROVIDER BY PROVIDER
A separate pace for every inbox provider
Gmail, Microsoft and Yahoo don't behave the same way, so they don't get treated the same way. Each one gets its own sending rate for your campaign, set from how that provider is responding right now, not a generic rule borrowed from somewhere else.
That means a campaign can move briskly through Yahoo while easing more carefully through Gmail on the same afternoon, because that's what each provider is telling us to do.
Rate set per provider, not one blanket speed
Adjusted live from current response
No guessing, no generic schedule

STEADY DOES IT
No catch-up bursts, ever
If an inbox provider asks us to ease off, we ease off. There's no hidden rule that tries to make up lost time later with a burst of mail, because a burst is exactly the pattern that damages trust in the first place.
That might mean a campaign finishes later than you expected. It's a trade we make on purpose: a slower finish keeps your domains trusted, which is what gets your next campaign into the inbox too.
No bursts, no exceptions
A later finish instead of a spike
Protects the campaigns still to come
DOMAIN BY DOMAIN
Spread across your sending domains
Every campaign is spread across your sending domains instead of leaning on just one. Each recipient's message is fully aligned to the single domain that carries it: the From address, the links and the footer all match, every time.
Spreading the load protects you two ways. No single domain carries all the risk of a big send, and every recipient sees a consistent, trustworthy sender rather than a patchwork of mismatched details.

Every message fully aligned to its domain
New domains earn more volume gradually as they're accepted

WHAT IT MEANS FOR YOU
Your mail gets there, without the stress.
Pacing isn't a setting you manage. It's just how every campaign leaves.
Your pace, trusted by every inbox
Every campaign reads the room before it leaves: steady where a provider wants steady, brisker where it doesn't. You never touch a dial.
Spread across your domains
Every campaign is shared across your sending domains instead of resting on one. No single domain carries all the risk of a big send.
Reputation, protected
New domains start small and earn more volume as inbox providers accept their mail. Nothing gets rushed past what's been earned.
99.7% delivered
Across our whole network, 99.7% of mail sent is accepted by the receiving mail servers. Pacing is a big part of why.
No catch-up bursts
If a provider asks for a slower pace, your campaign takes a little longer to finish instead of spiking to catch up.

QUESTIONS
Deliverability, answered

Why does my campaign take a while to finish?
Because it's paced to what each inbox provider will accept. A campaign that finishes a little later keeps your domains trusted, which is what gets the next one into the inbox.
What does 99.7% delivered mean?
Across the whole network, 99.7% of the mail sent is accepted by the receiving mail servers.
Will sending to my whole list at once hurt my domain?
It can. A sudden flood of mail reads like the pattern spam filters watch for, and one bad afternoon can sink a domain's reputation for weeks. That's exactly why we pace every send instead.
Does every inbox provider get treated the same way?
No. Gmail, Microsoft, Yahoo and the rest each get their own sending rate, adjusted from how that provider is responding to your mail right now.
What happens if a provider asks you to slow down?
The campaign takes a little longer to finish. There's never a burst to catch up, because a burst is exactly the pattern that damages trust.
How does pacing work across my sending domains?
Each campaign is spread across your sending domains, and every recipient's message is fully aligned to the one domain that carries it: From address, links and footer all match.
Do new sending domains start at full speed?
No. Every new sending domain builds its reputation gradually, starting small and earning more volume as inbox providers accept its mail.
