Mailtrain

List Management Mailtrain allows you to easily manage even very large lists. Million subscribers? Not a problem. You can add subscribers manually, through the API or import from a CSV file. All lists come with support for custom fields and merge tags as well. Custom Fields Text fields, numbers, drop downs or checkboxes, Mailtrain has them all. Every custom field can be included in the generated newsletters through merge tags. Mailtrain also supports custom forms. List Segmentation Send messages only to list subscribers that match predefined segmentation rules. No need to create separate lists with small differences. RSS Campaigns Setup Mailtrain to track RSS feeds and if a new entry is detected in a feed then Mailtrain auto-generates a new campaign using entry data as message contents and sends it to selected subscribers. GPG Encryption If a list has a custom field for a GPG Public Key set then subscribers can upload their GPG public key to receive encrypted messages.
