1and1Mail screenshot1and1Mail is a lightweight and efficient software utility designed for small and medium businesses. This tool will help users promote their company by sending personalized mass emails. It also features a tracking option, that will let users determine how efficient their campaign is.

1and1Mail offers the Auto IP Switcher feature, which will automatically change your IP address using various proxy servers in order to avoid your email address being blacklisted. This is useful if you are sending mass emails from multiple email accounts registered to the same service provider. The software will also change the content of your emails and will make them look different for each recipient.

1and1Mail reduces the chances for you to get blocked or blacklisted by your email service providers by using the "Random Time Lag", which will mimic manual email sending. This software also keeps your information and address list safe by letting you establish role-based passwords.

1and1Mail allows you to save email templates from various websites and use them in your campaigns to impress your clients. It also has the capability of cleaning unsubscribed or bounced email messages, avoiding your email address to be suspended due to bounce-backs and spam complaints.

1and1Mail also offers the "Multi Account Manager" feature which will increase the number of emails you can send on a daily basis without being considered a spammer. Another great feature is the WYSIWYG (What You See Is What You Get) HTML Editor which will help you build newsletters fast and effortlessly. Advanced users have also the possibility to edit the HTML code source for giving a finishing touch or fix their emails' layout.

1and1Mail lets you send personalized email messages to all your customers, allowing you to customize the subject, salutation and email body. This software also allows you to create multiple contacts groups in your address book. You can easily manage your contacts, import addresses from other sources (.XSL .CSV, .TXT), or customize address book fields according to your needs.
