When managing SMS and email subscribers in Delivra, it's helpful to know whether a contact’s email and mobile number are linked within your account. This connection determines how easily you can manage, segment, and communicate with contacts across channels.
Whether or not a subscriber’s email and SMS records are linked depends on how the contact was added to your Delivra account. In some cases, the platform automatically creates a link between the two identifiers—email and mobile number—while in others, they remain separate records.
Here’s what you need to know:
Some data entry methods don’t automatically associate a contact’s email address with their SMS number. These include:
Forms that collect only one identifier
If your subscription form asks only for an email or SMS number (along with opt-in consent), Delivra will create two separate contact records.
SMS keyword opt-in without email capture
If your SMS keyword campaign is set up to only request and confirm a mobile number, the contact will be added to your SMS list without an associated email.
In both examples, email and SMS data are stored separately in the system.
To link email and SMS under a single contact profile, both data points must be submitted together. This typically occurs when:
Your form collects both email and SMS information
A well-designed subscription form that captures both fields will ensure the contact is linked in Delivra.
You import data using a CSV file that includes both fields
During import, Delivra will link the email and phone number as long as both are present in the same record.
Your API call includes an email address when adding an SMS contact
If you're using Delivra's API, be sure to include the EmailAddress field when submitting SMS contact data to create a link between the two.
Design your subscription forms to capture both email and SMS to ensure smooth contact management and reduce duplicates.
Include both data points when importing contacts or integrating via API to maintain data integrity.
Review your opt-in workflows to determine where linking might be beneficial—especially for multichannel campaigns.
A retailer wants to send promotional emails and last-minute SMS alerts to loyalty members. If email and phone number are linked, they can manage communication preferences from a single contact record.
A nonprofit runs an SMS fundraising campaign but later wants to follow up by email. If the original opt-in didn’t capture email, they’ll need to request it separately.
