Yes email marketing is like any other marketing programme – it is a numbers game, the more you send, the more chances that more people will open your email - but there is a LOT MORE to email marketing than just blasting out numbers!
A quality list of end users or subscribers who have agreed to receive your email and have opted-in will get you results. The opted-in process works like this – a potential subscriber completes a signup form on your website or through an email invitation and submits it to you, then an email is sent back to that person asking them to validate or give you permission to send them email. Now you have an end user who is qualified as a valuable lead and is expecting to receive an email communication from you in the future. Now your chances of those qualified leads reacting to your email is going to be a lot more positive.
An email sent to a qualified list is most certainly going to get a much higher “open rate” from subscribers who open the email and become exposed to your marketing message.
Email marketing is very much a process that does work if it is done right.
