My company is launching over the summer and we are beginning to accumulate emails of potential users. When the time is right I plan on using hubspot for all my email marketing needs but until then I need a place to store the emails we have already collected.
My first question is, how did you get these email addresses? If they physically entered them, simply store them in an encrypted spreadsheet or database for importing into a platform.
Of course, the best method is utilizing an email service to initially collect those addresses.
