If you have a file with your customers' phone numbers, you can upload it to Selzy. Then you can send them an SMS newsletter.
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.
Required fields
In Selzy, there is one required field — "Email". Therefore, to upload a contact, the contact row must also include the email address along with the phone number.
Contacts without email addresses will not be uploaded.
If you don't have email addresses, you can add stub addresses instead.
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, +79161234567 or 79161234567 are correct formats.

Frequently asked questions
How to import phone numbers without email addresses
This is no such possibility, but you can add stub addresses instead of actual email addresses.
Here we show how to do this in Excel
For example, we have a file with three columns - "Email", "Phone", "Name". In some rows, the Email field is filled in, in some it is not.
You need to fill in all cells in the column with email addresses.
To do this, copy the formula and paste it into a new column:
IF(ISBLANK(A2);B2&"@example.com";A2)
Then double-click on the plus sign in the lower right corner of the cell to multiply the formula to the entire column.
How this formula works:
- If a cell in the email column is filled in, its value is transferred to the current cell.
- If a cell in the email column is empty, a new email stub is created in a format [email protected], where XXXXXXXXXXX is the phone number from the "Phone" column.
Important!
The formula works correctly if email addresses are in column A and phone numbers are in column B. If your file has a different column positioning, change their positions or insert letters of the desired columns in the formula.
Now let's replace the old column containing email addresses with a new column.
To do this, enter "Email" in the upper cell, copy the entire column and paste it instead of the old one. When pasting, it is important to select "Values", as shown below. If you just insert text, the formulas inserted will not work.
The file is ready for import.
How duplicates are imported
Since the” Phone” field is optional and the “Emai”l 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:
| Phone | Name | |
| [email protected] | +79101234567 | Irina |
| [email protected] | +79101234567 | Sergey |
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:
| Phone | Name | |
| [email protected] | +79101234567 | Irina |
| [email protected] | +79687654321 | Irina |
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 that start with "8"
If the list contains Russian phone numbers that start with "8", and not "7" or "+7", 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 "8", while in some with "7" or "+7".
To fix the numbers that start with "8", use the formula:
IF(AND(LEN(B2)=11;LEFT(B2)="8");("7"&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 "8", but the number has 11 digits in total, then the first digit changes to "7".
- 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 select "Values", as shown below. If you just insert text, the copied formulas will not work.
The file is ready for import.
