Every contact in Omnisend has a profile that stores personal details, engagement history, and custom data. You can manually update email addresses, phone numbers, tags, custom properties, and more directly from the Contact Profile.
This article shows how to edit contact data without creating duplicates or losing information.
Before You Begin
Editing contact data updates existing information and adds missing values. It won't create duplicates or overwrite the profile.
Any changes to a contact's profile can impact the segments and automations the contact is in.
Access Contact Profile
The Contact Profile stores all available data for each contact, divided into two areas:
Contact Details: Personal data, including subscription status, email, name, address, tags, etc.
Activity Timeline: Engagement events like placed orders, opened messages, entered segments, etc.
You can manually edit all Contact Details individually, updating existing values or adding new ones.
Go to Audience → Contacts → Search for the contact → Click to open their profile.
Edit General Data
Under General, you can edit key contact details, including contact identifiers (email address and phone number) and first and last name.
To update these details, open the contact profile → Click Edit → General.
Updating Contact Identifiers: Email Address and Phone Number
Contact identifiers are the primary data points that define a contact profile: email address and phone number. A contact can have one or both. All future data, including purchases or behavior, syncs to the profile based on these identifiers.
⚠️ Important: Omnisend uses email as the primary identifier. Here's how matching works:
If the email matches an existing contact but the phone differs, the phone is updated.
If the email matches one contact and the phone matches another, data merges into the email-matched contact, and the phone is ignored.
💡 Recommendation: Update identifiers inside Omnisend first, then in your store platform. Editing them only in the store may create duplicate contacts in Omnisend.
Edit Additional Data
Under Additional data, you can edit and add:
Location details: Address, Country, and Postal/Zip code.
Birthdate: Year, month, and day.
Gender: Female or Male.
To edit this data, open the contact profile → Click Edit → Additional.
Edit Custom Data
Under Custom Data, you can edit and add Custom properties, which are additional data fields used to store information unique to your contacts, such as loyalty status, signup source, or any other custom value you define. Learn more about Custom Properties.
To edit custom properties, click Edit → Custom. You can then:
Update existing properties with new values.
Change or remove current values.
Add new custom properties with corresponding values.
Note: Custom Property names cannot be changed after creation. To rename a property, create a new one, then re-import your contacts with the updated property name. Learn more about importing contacts.
Edit Tags
Tags are labels used to organize and segment your contacts based on shared characteristics or actions. Learn more about Tags.
To edit Tags, scroll down to the Tags section:
To add new tags, click the Add button → Type the tag name → Select an existing tag or create a new one.
To remove existing tags, click the X next to the tag you want to remove.
Tip 💡 For bulk tagging, go to Audience → select contacts (check individual boxes or use the checkbox next to "Name" to select all) → click the Actions button → Add Tag or Remove Tag.
Note: Tag names cannot be changed after creation. Double-check spelling before creating a new tag.
Edit Subscription Status
You can manually unsubscribe a contact from Email, SMS, or Push channels. This is especially useful if a customer requests to stop receiving messages through a specific channel.
To unsubscribe a contact, click the dropdown arrow next to the Edit button→ Unsubscribe → Select channel → Unsubscribe.
💡 If you’ve unintentionally unsubscribed a contact and need to resubscribe them, check our dedicated article for step-by-step instructions.
FAQ
Can I edit a contact's order history?
No. Order data syncs from your store's ecommerce platform. To correct it, you will need to edit and re-sync from your store.
What happens if I change an email address that's in a segment?
The contact's segment membership updates automatically based on the new identifier.
Will new contacts entering my segment automatically get tagged?
No, bulk tagging only applies to contacts currently in the segment. To automatically tag new contacts as they enter a segment, create an automation: set the trigger to "Contact entered segment," then add a Tag block.
