Though our automate email software – Auto Mail Sender supports importing recipients from .txt, .csv, .xls and .xlsx files, but we recommend you to prefer the .txt or .csv files. Because importing a plain .txt or .csv file to our automate email software – Auto Mail Sender is very fast, .xls(x) is not due to connecting to the Excel application, data format converting.
Specially, if a file contains thousands recipients, the difference is obvious.
So, if your contacts stored in the Excel document, please save it as .txt or .csv file first, and then import them to our automate email software – Auto Mail Sender.
