Quick Answer

Seed emails are InboxAlly-owned email addresses that you include in your sends. InboxAlly’s AI system interacts with your emails through real mailbox interfaces — opening, clicking, and moving them to inbox — which signals to providers like Gmail and Yahoo that your mail is wanted. This builds sender reputation and improves inbox placement over time.

Seed emails are dedicated email addresses owned by InboxAlly that you add to your sends so our AI system can interact with your campaigns — opening, clicking, replying, and moving messages to the inbox through real mailbox interfaces. These engagement signals teach providers like Gmail and Yahoo that your mail is wanted, which builds sender reputation and improves inbox placement over time.

What Are Seed Emails?

Seed emails are InboxAlly’s own email addresses, hosted across major providers like Gmail, Yahoo, and Microsoft. You include them in your sends alongside your regular subscriber list. When our system receives your messages, it interacts with each one through the native user interface of the email platform — not via an API or background script.

This distinction matters. Email providers can tell the difference between real engagement and automated signals. By working through native interfaces, InboxAlly’s AI generates opens, clicks, replies, stars, and inbox moves that providers interpret as genuine user behavior. Over time, these signals build your sender reputation and improve inbox placement across your entire send volume.

How to Set Up Seed Emails

Step 1: Download your seed list

Navigate to the Seed Emails page in the InboxAlly app (left navigation bar) and download your full set of seed email addresses. You can send to your entire seed list or a portion of it — the full list gives you the most engagement data and strongest impact.

Step 2: Create a Sender Profile

Go to the Sender Profile page and create a new profile. This defines the engagement rules that InboxAlly applies to your emails — which actions (opens, clicks, replies, stars, inbox moves) our system performs on each send.

Step 3: Choose an engagement preset

On the Sender Profile page, select an engagement rule preset that matches your goal. Some presets maximize opens and clicks for engagement campaigns; others prioritize inbox moves for new or recovering domains. You can also adjust individual settings for more control.

Engagements are applied randomly each night at 12:00 AM based on your profile’s local time, so the interaction pattern looks natural to providers.

Step 4: Add seed emails to your sends

Import the downloaded seed addresses into your email sending platform and add them to the same list or segment you use for regular campaigns. Our system will interact with most seed emails within 4 hours of sending, with engagement starting within the first hour. No additional steps are needed — the system handles everything based on your Sender Profile.

Monitoring Your Results

Track seed email performance in two places:

Broadcasts (left navigation bar) — engagement data for individual sends including open rates, click-through rates, and inbox placement
Reports / Dashboard — trends over time across providers, helping you refine your sending strategy

Frequently Asked Questions

Can I send to only part of my seed list?

Yes. The full list gives you the most data and broadest impact, but partial sends still generate valuable engagement signals.

How quickly will I see results?

Most users see initial improvement within one to two weeks. Full reputation building typically takes four to eight weeks of consistent sending.

Do seed emails work with every type of email?

Yes — promotional campaigns, newsletters, transactional messages, and re-engagement campaigns all benefit from seed email engagement.

What happens if I stop using seed emails?

Without the engagement signals seed emails provide, your sender reputation may gradually decline, especially if regular subscriber engagement is low. For best results, keep seed emails as a permanent part of your sending routine.
