Seed lists that place your campaigns in the inbox. Every campaign has a number on it. Seeds protect the number.
Real consumer Gmail and Outlook inboxes on your recipient list. When the campaign lands in spam or promotions, the seeds move it to the inbox, mark it important, and read it. You see inbox, promotions, or spam per provider, on the real send.
What every seed does with your email. Four things, on the real send.
- 01Opens it.
On a real consumer Gmail or Outlook inbox, on a real device profile.
- 02Rescues it from spam.
Moves it to the inbox and marks it not spam, the direct correction opens-only tools cannot make.
- 03Dwells on it.
Reads for a human length of time, varied seed by seed, the way a list of real recipients would.
- 04Marks it important.
A small share of the seeds do, a positive signal the provider records.
Not spam. Just promotions. That is where half your list stops seeing you. The offer, the design and the segment were built for the whole list.
Your tool reports sent. Gmail and Outlook decided promotions, and neither told you. A seed list shows the real send the way a consumer inbox sorts it, and does something about it.

Two ways to use a seed list. Protection during a real send, or signals built before it.
Export a batch of seeds into the list, send as usual. When the campaign hits spam or promotions on a consumer inbox, the seeds pull it out and engage, so a send that goes wrong is contained instead of carried into the next one.
- 01Export seeds into the campaign list.
- 02Send the campaign as usual.
- 03Seeds open, rescue, dwell, mark important.
Send the campaign to a seed batch before the real list. The seeds engage with the content and the domain, so the list with the number on it goes out on a domain and content Gmail has already seen engaged with.
- 01Export a seed batch on its own.
- 02Send the campaign to the seeds.
- 03Then send to your real list.
Placement you can see, provider by provider.
Your revenue per campaign is your figure. Placement per provider tells you how much of the list it was earned on, and where the rest went. Open rates will not tell you: they are falsely reported more often than not. Knowing it is Outlook and not Gmail changes the fix.
Today the seeds cover Gmail and Outlook, the consumer inboxes B2C senders actually reach.

A set of real consumer mailboxes you add to your recipient list. They report where your campaign landed, inbox, promotions, or spam, per provider, and MailStrike's seeds go further: they move mail out of spam, mark it important, and read it.
Warming builds your domain's reputation before and between sends, through an AI Agent on each mailbox. A seed list protects a specific send while it happens, or builds signals for it just before. Seeds protect the send. Warming builds the sender.
Today, Gmail and Outlook: the consumer inboxes B2C senders reach. That is where the promotions tab and the junk folder live.
No. You export the seeds as a CSV into whichever tool sends your campaigns and publish one DNS TXT record. Nothing changes in the sending stack.
Yes. Moving mail out of spam and marking it important contradicts the provider's decision, and the provider records it for your domain as a positive signal.
Yes. Seed Lists are a standalone product priced by seed volume. You do not need a warming plan to use them.
B2C senders: ecommerce, newsletters, product companies reaching consumer Gmail and Outlook inboxes. B2B senders reaching business mailboxes should look at warming instead.
