Appalling company to deal with, no contact telephone number on their website, shambolic technical support. Mailchimp are your typical hide behind a website, non human USA company.There is a real danger you could get locked out of your account and lose all your customer data, support will not help you get back in.Do yourself a favour and avoid them, there are so many better email marketing companies you can deal with, we moved to Dotmailer and have never regretted it.
