How to Import Phone Numbers

If you have your customers' phone numbers, you can upload them to Selzy and use them to personalize content of your emails.

Preparing the file

File format and size

Files in CSV, XLS, XLSX, and TXT formats are suitable for uploading.

XLS and XLSX files may have additional formatting elements, table borders, formulas, merged cells, and other elements that prevent importing the data correctly"(present tense). Therefore, we recommend that that you save your XLS and XLSX files as CSV files.

The file encoding is UTF-8.

The maximum file size is 20 MB.

The maximum number of columns in a file is 50.

Format of phone numbers

Phone numbers must be in international format, starting with the + symbol and the country code, or starting with the country code. For example, +551234567890 or 551234567890 are correct formats.

Importing a file

In your account, go to Contacts — All Contacts and click on the Add Contacts button. The button is also available from the Lists tab and from every email list.

Choose Import contacts, if you want to upload a file or Add one contact for adding phone numbers manually.

The import page opens.

There are two ways to import contacts:

From file. Click Upload a file and select the file to be imported, which meets the requirements.

Manually. Go to the Manually tab, add the contacts you want to upload and click Continue.

Next, configure the fields. Set the required field Email. Next to the phone numbers, select Mobile phone number. Click Continue.

Select the contact list and click Import.

Data import is completed.

If errors occured during import, click "Error Report" to download the report.

In the report, you can see why not all contacts were imported and the reasons for errors. These can be, for example, duplicate contacts, errors in email addresses and phone numbers.

Frequently asked questions

How duplicates are imported

Since the Phone field is optional and the Email field is mandatory, the system will only check email for uniqueness. You can import phone number duplicates to the list if the email addresses are different.

Examples:

1.Uploading two contacts:

The phone numbers are the same, but the email addresses are different, so both contacts will be added to the list.

2.Uploading two contacts:

The phone numbers are different, but the email address is the same, so only one contact with a phone number which is imported last will be added to the list.

How to replace phone numbers

If the list contains phone numbers with an incorrect or outdated country code, you need to fix them. In Excel, you can do this in bulk.

Let us assume, we have a file with three columns - "Email", "Phone", "Name". In some cells, the phone number starts with "0" (local UK format), while in some with "44" or "+44".

To fix the numbers that start with "0", use the formula:

=IF(AND(LEN(B2)=11;LEFT(B2)="0");("+44"&MID(B2;2;10));B2)

Copy it and paste it into an empty cell in an empty column. Then double-click on the plus sign in the lower right corner of the cell to apply the formula to an entire column the formula to the entire column.

How this formula works:

• If the first digit in the phone number is "0", but the number has 11 digits in total, then the first digit changes to "+44".
• In all other cases, the number remains the same.

Important!

The formula works correctly if the phone numbers are in column B. If your file has a different column positioning, change their positions or insert a letter of the desired column in the formula.

Now let's replace the old column containing phone numbers with a new column.

To do this, enter "Phone" in the upper cell, copy the entire column and paste it instead of the old one. When pasting, it is important to use values from the copied cells. If you just insert text, the copied formulas will not work.

The file is ready for import.
