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.
Text fields, numbers, drop downs or checkboxes, Mailtrain has them all. Every custom field can be included in the generated newsletters through merge tags.
Send messages only to list subscribers that match predefined segmentation rules. No need to create separate lists with small differences.
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.
If a list includes a custom field for a GPG Public Key then subscribers can upload their GPG public keys when signing up or managing preferences. Subscriber that have a key set get all messages from the list in an encrypted form.
After a campaign is sent, check individual click statistics for every link included in the message.
Mailtrain is available under GPLv3 license and completely open source.
