Question 1

What is an email seed list?

Accepted Answer

The email seed list comprises a curated selection of genuine email addresses from Gmail (in the near future Outlook addresses too). These addresses act as “seeds” to test your emails’ performance on various platforms and in various filters, which improves your deliverability in the end

Question 2

Why are email seed lists important?

Accepted Answer

Seed lists ensure your emails land in the inbox by warming up your sender reputation — without them, ISPs have no reason to trust your domain, and your campaigns risk ending up in spam before they even reach real subscribers.

Question 3

What is the power of a seed list?

Accepted Answer

Our warm-up seed list’s main objective is to get your email, IP, domain, and template ready before launching your real campaigns. We open, filter out, and read your template when you submit it to the seed list. This procedure makes sure that email providers view your emails as relevant and important, which greatly improves your deliverability

Question 4

How can a seed list benefit your email marketing?

Accepted Answer

To put it simply, the email seed list is a tactical tool for negotiating the challenges associated with email deliverability. You can improve your campaigns, increase engagement, and get better results by utilizing its power. To realize the most results from your email marketing campaigns, adopt a proactive approach to testing, optimization, and adherence to best practices

Question 5

Can using an email seed list improve my email open rates?

Accepted Answer

Yes, you can increase email open rates by employing an email seed list. You can assist email providers in learning to identify your emails as real and not spam by submitting them to the seed list first. By doing this, you not only boost the likelihood that your emails will be sent successfully overall, but also that the recipients themselves will notice and open them

Question 6

How do I use the Warmy seed list?

Accepted Answer

It takes three steps. Request and download the latest seed list from your Warmy dashboard before every campaign, add those addresses as a segment or list inside your email platform, then send your campaign to them exactly as you would to real subscribers. Our seed mailboxes open, read, click and rescue your message from spam, and you get a placement report showing where the email actually landed.

Question 7

Which email platforms does the seed list integrate with?

Accepted Answer

Any platform that lets you import a list or create a segment works — Klaviyo, Mailchimp, HubSpot, ActiveCampaign, Brevo, Customer.io, SendGrid, Amazon SES, Mailgun, Salesforce Marketing Cloud, Omnisend, GoHighLevel and dozens more, plus any custom SMTP or in-house sending system. There is nothing to install: you simply send to the seed addresses from your existing setup.

Question 8

Can the seed list be automated?

Accepted Answer

Yes. Warmy refreshes the seed list automatically, so you always pull fresh, actively used mailboxes, and every send to those addresses is engaged with automatically — opens, replies, spam rescues and folder moves happen without any manual work from your team. Teams running scheduled campaigns simply include the seed segment in their recurring send and review the placement report afterwards.

Question 9

Can I pull the seed list through the Warmy API?

Accepted Answer

Yes. The Warmy API lets you fetch the current seed list programmatically and push it into your sending platform or internal tooling, so seed testing becomes part of your automated release process instead of a manual step before each campaign.

Question 10

How often should I refresh and re-send to the seed list?

Accepted Answer

Download a fresh copy before every campaign, and at minimum weekly if you send continuously. Seed mailboxes rotate to stay genuinely active, so an outdated list gives you a less accurate picture of your inbox placement.
