It happened the other day. I was with a client who had a large number of email addresses copied to his computer clipboard. He pasted them into Microsoft Excel and then saved the document as a CSV file. Only then could he properly import them into Interspire Email Marketer.
There is a better way. Using the “Add Contacts Via Paste” addon for Interspire Email Marketer you can quickly access a new menu in IEM where you simply select the contact list, the separator (line, space, comma) and paste the contacts. That is it. The addon is extremely efficient and has been tested with up to 50,000 contacts in less than one minute.
