In this step, you will add your opted-in email subscribers using supported collection methods. Your subscriber base should include opted-in, reachable email addresses with correct identity mapping to ensure successful delivery.
A subscriber base is important as it:
- Is a properly configured subscriber base.
- Helps prevent spam complaints and GDPR risks.
- Improves IP warm-up and deliverability.
- Ensures campaigns reach real, engaged users.
- Provides more accurate analytics and segmentation.
Without a valid subscriber base, your campaigns may face bounces, suppression, and low reachability.
View your email subscriber base
In the Subscriber Base step, you can see your Subscriber Readiness. In this section, you can see the difference between your expected subscriber count, which is also shared in the Key Email Information step, and your actual uploaded/integrated email subscriber count.
Additionally, in this section, you will find the required user attributes to send to Insider One for your email subscriber base.
Upload your email subscriber base to Insider One
To send out email campaigns to users, your brand must first receive specified, explicit, and legitimate opt-in permission confirming that the users wish to receive email messages from your brand. This opt-in must clearly state that this user is opting in to receive messages from your brand over the Email channel, and clearly state your business' name.
You can collect or share your users' consent information with the following methods:
Lead Collection Templates
Insider One's desktop and mobile web lead collection templates help you collect your users' email addresses and their opt-in information. When your users give their consent to receive marketing content from your brand while sharing their email addresses with you, Insider One automatically logs this information. In this case, you do not need to share any consent information for these users with Insider One.
Web SDK for Email Integration
Web SDK is a JavaScript array integration that helps you share your users' consent to receive marketing content from your brand with Insider One. Read more on Email Integration.
Upsert User Data API
Upsert User Data API is one of Insider One's external APIs that you can call from your back-end. It helps you pass your users' consent information from your back-end (e.g., call center, CRM, etc.) to Insider One. Read more on Upsert User Data.
Saved Static Segments
Saved static segments help you create your segments and use them on the Recipients step. Read more on Saved Segments.
Opt-in alone is insufficient to target users via email. To receive emails from your brand, users must be reachable—meaning they are active subscribers to your email channel.
A reachable user has a valid email address, has explicitly given consent, has not had emails bounce, has not marked emails as spam, and has not unsubscribed from email campaigns. Maintaining a high percentage of reachable users enhances email deliverability, boosts engagement rates, and improves overall campaign effectiveness.
