How to import contacts into Meser10
Upload a CSV or Excel file and your contacts are ready for your next campaign. Four short steps, with screenshots.
Prepare an Excel (xlsx) or CSV file with one sheet, one contact per row and the column names in the first row, for example Email address, First name and Last name. Sign in at app.mesereser.com and follow the steps below.
1. Open Import Contacts
In the side menu, click Contacts and then Import Contacts. You can also start from Import Contacts under Get started on the home screen.

2. Choose the list
To start a new list, type its name under Create a new list. To add the contacts to lists you already have, tick them under Existing lists. Then click CONTINUE.

3. Upload the file
Drag your file into the box, or click Choose a file to upload and pick it from your computer.

4. Match the columns
The system shows the columns of your file on the left. Under Match Columns, each one starts as (Unmatched). Choose E-mail for the email column, and First name and Last name for the name columns. Hover over a column to preview its values on the right. When every column you need shows a check mark, click CONTINUE.

The system shows how many records were imported out of the rows in the file. Duplicate or invalid addresses are not imported. You can now choose the list as the recipient list of your next campaign.
Tip: if you exported the list from another system, export only the active contacts. Contacts who unsubscribed from your account stay unsubscribed even if they appear in the file.
