Warm-up, explained.
Before Slingshot sends a single real email for you, your mailboxes spend a fortnight earning a reputation. Here’s what that means, why it matters, and what you’ll see while it happens.
What it is.
Mail providers decide where an email lands — inbox or spam — by what they know about the sender. A brand-new address has no history, so it has no trust.
Warm-up gives it a history. Your mailboxes exchange ordinary, friendly emails with a network of other warmed mailboxes, replies included. If one of those lands in spam, it’s pulled out and marked as wanted. Day by day, the providers learn that mail from your address is opened, answered and kept.
It runs in the background. Nothing for you to do, and nothing for your clients-to-be to see.
Why it matters.
Reputation is earned
Sending forty emails a day from a new address on day one is the fastest way to be marked as spam — and that mark follows every email after it. Two weeks of patience buys months of landing where you’re meant to.
Your real domain stays out of it
Slingshot sends from a sending domain alongside your real one. The reputation at stake is the outreach domain’s; your main address, your invoices and your staff’s mail are never on the line.
Landing is the whole game
An email that reaches a spam folder costs the same as one that reaches a person and achieves nothing. Warm-up is the difference between reaching people and reaching filters.
How Slingshot does it.
A fortnight, paced. Each mailbox starts small and ramps up until it’s sending at a steady, believable level — then real sending begins.
What you’ll see.
The Mailboxes page shows each mailbox’s warm-up against the plan, and the dashboard shows the whole picture until the day you go live.
Fair questions.
Do I need to do anything?
No. Warm-up starts the moment a mailbox is connected and runs on its own. The dashboard shows which day it’s up to and the date you’ll be ready to send.
Can we skip it?
No, and you wouldn’t want to. A fortnight is cheap insurance against months of mail landing in spam — and because billing starts at your first real send, the warm-up weeks cost you nothing.
Does it ever stop?
It keeps running quietly after you go live, alongside real sending, so the reputation it built is maintained rather than spent.
Will warm-up mail clutter my inbox?
No. It’s filed out of the inbox by default. If you’d like to see it, there’s a switch on the Mailboxes page.
See it live, built around your business.
