newsletter being fixed in form and monotonous in content is highly possible to be caught bouncing. To increase the chance of your mailings getting into your target account recipients’ inboxes, we strongly recommend that you personalize your newsletter.
Our Customize Fields feature make it easy to personalize it on the receiving end.You can personalize your email with your contacts’ names, email addresses, company and other information.
