It’s likely a lot of your subscribers will also have a twitter account. We added a field to our signups to enter this, but some people are a little lazy or don’t see the value in adding it.
Twitter has a ‘find friends’ feature that allows you to search email addresses for twitter users though, so it’s quite easy to follow people on your list.
Export your mailchimp list and import it into a new email account. We use Gmail.
Now ask twitter to search this account, click the box in gmail that allows it and twitter will check the list for matching accounts.
We found over 400 people who had signed up but we weren’t following.
This is a useful extra point of contact since some people might have signed up but not realised you also had a twitter account.
As a bonus tip you can also import this list into Angel List to easily find out who might be interested in investing capital….
