In this article, we will explain how to format your contact import file.
When you import contacts to Sendinblue, the data of your import file will be matched to contact attributes in your Sendinblue account. Certain types of contact attributes, like EMAIL and SMS, require a specific format to be imported correctly.
Good to know
There are 4 default attributes in Sendinblue when you create an account: FIRSTNAME, LASTNAME, EMAIL, and SMS. The FIRSTNAME and LASTNAME default attributes name may vary based on the account language you selected during your account creation.

The following file types are compatible when importing your contacts to Sendinblue:
- .CSV (Microsoft Excel, OpenOffice Calc, Google Spreadsheets)
- .XLSX (Microsoft Excel open format)
- .TXT (Microsoft Notepad)
Column headers are optional but make it easier for our system to match your data to the corresponding contact attributes. Each column in your file needs a unique name and you can arrange them in any order. To simplify the import, use your contact attribute names as the headers in your file. If you don't include column headers in your import file, you will need to manually match each column with a contact attribute.
Each value in your import file must be separated by a semicolon
;, a comma
, or a tab
To import a contact email address, use the EMAIL default attribute as your column header.
To import the phone number of a contact you want to send SMS messages to, use the SMS default attribute as your column header. Always include the + sign and the country code for each phone number, and do not separate the digits by any special character.
To import the phone number of a contact you want to send WhatsApp messages to, use the WhatsApp default attribute as your column header. Always include the + sign and the country code for each phone number, and do not separate the digits by any special character.
Text type attributes are used to store a string of any alphanumeric characters, such as a word, a phrase, or a sentence. You can use a text type attribute to import additional data such as your contact's language preferences, favorite color, or company name. When used in an import file, Text type attributes have no limit of characters.
Number type attributes are used to store a string of numerals or numbers written in decimal. You can use a number attribute to import numbers or currency values to your contacts.
For example, if you have an opt-in value, you can create a Boolean type attribute named OPT_IN which can only contain empty, Yes, or No as values.
Category type attributes are used to store values which can contain only one value from a defined set of possible values.
For example, if you have a gender value, you can create a Category type attribute named GENDER and define possible values as “Female”, “Male” or “Unknown”. The attribute GENDER of each contact will then only contain one value among “Female”, “Male” or “Unknown”.
In your import file, only include the category option ID number. For example, you could have:
- 1 if the GENDER attribute is “Female”
- 2 if the GENDER attribute is “Male”
- 3 is the GENDER attribute “Unknown"
Import file examples
- Each contact must have their own row.
- Each column must include a single piece of information.
- Each contact must have their own line.
- Separate each value by a semicolon
;, a comma
,or a tab
