The seed phrase is one account-level text string that Winnr adds to every warmup email your mailboxes send. Its only job is to be a marker: set a filter in your sequencer's unibox or your mail client that matches that exact phrase, and warmup mail sorts itself out of your way. Set it in the "Warmup seed phrase" card on the Warming page (up to 2,048 characters). It applies to all your warming mailboxes and does not change warming performance.
What the seed phrase is for
Warming runs in the background, but warmup messages still pass through the mailboxes you're warming. If those mailboxes are connected to a sequencer or a mail client, warmup mail can clutter your view.
The seed phrase fixes that. Because the phrase is always present and always the same, one filter catches all of it:
- Pick a distinctive phrase (for example
winnr-warmup). - Winnr adds it to every warmup email your mailboxes send.
- You add a matching filter in your sequencer or mail client that archives or labels anything containing the phrase.
One phrase, whole account
This is a single account-level setting. There's one text field and one phrase, and it applies to every warming mailbox. You don't write warmup content; Winnr handles the actual warmup messages.
What it does not do
- It does not speed up or improve warming. Volume and ramp speed drive warming.
- It does not change your cold campaigns. Campaign copy lives in your sending tool.
- It is not seen by the people you cold-email.
What's next
Step-by-step
-
1. Open the Warming page
App sidebar → Warming. The "Warmup seed phrase" card sits below the summary cards at the top. (It appears once at least one mailbox is warming.)
-
2. Enter a phrase
Type a short, distinctive marker in the field (the placeholder suggests something like "winnr-warmup"). It's one field and one phrase for the whole account, not a list.
-
3. Save
Click Save. Winnr applies the phrase to all your warming mailboxes in the background, and mailboxes you enable later get it automatically. Warmup emails already sent don't change.
-
4. Add a filter on your side
In your sequencer's unibox or your own mail client, create a filter that matches the exact phrase and archives or labels it. Warmup mail then stays out of your main view.
Frequently asked questions
Does the seed phrase change warming performance?
No. It has no effect on reputation, volume or how warming runs. It's purely a marker for filtering.
Is it per mailbox or account-wide?
Account-wide. One phrase applies to every warming mailbox on your account.
What makes a good phrase?
Something distinctive that won't appear in your real mail. A short slug like "winnr-warmup" or a unique token works well.
How long can it be?
Up to 2,048 characters. In practice a short, unique marker is all you need.
Do I need it for Winnr's own Inbox?
No. Winnr's universal inbox already hides warmup mail from Winnr's warming network automatically. When you save a seed phrase, Winnr also adds it to the inbox's Warmup Exclusions list for you. The seed phrase is mainly for filtering in other tools.
How do I remove it?
Clear the field and click Save. New warmup emails stop carrying the phrase.
Do the prospects I cold-email ever see it?
No. It's only added to warmup emails exchanged with Winnr's warming network. Your real campaign copy comes from your sending tool and never includes it.
