I'm just going to come out and say it;
You need to use a third-party autoresponder service.
If you're still sending emails from outlook, Gmail or using your own servers then you're leaving money on the table.
And if you're sending emails using mass BCC, please stop.
(Yes, some entrepreneurs are still doing this!).
An autoresponder service takes care of a lot of the headaches you can face in email marketing;
- Avoid your emails getting spammed
- Building a good relationship with the big name email clients (Gmail etc.)
- Ensuring high deliverability
- Dealing with segmentation, automation and unsubscribes
"You should use Getresponse like I do, because they have high deliverability, good prices and you can get hold of their support."
