API Method "ImportGroupMembersFromData" Improved

Previously, the maximum string size for the ImportData input parameter of the ImportGroupMembersFromData method was approximately 4 MB. This limit has been increased to 32 MB, which will allow for larger data sets to be imported at one time with this method.

How to do A/B split testing in JangoMail

It is very easy to conduct an A/B split test in JangoMail.

Using JangoMail Groups

If you are storing your e-mail lists in JangoMail Groups, you simply need to send one e-mail to one half of your Group and the second e-mail to the second half of your Group. You can easily split your Group in half using the "Filter and Send" feature.

1. Click the "Filter and Send" button.

2. Switch to the "Advanced Query Editor".

3. In the yellow "Tips" area, click link for "A/B split testing". This will populate the SQL SELECT and WHERE clauses.

4. Click the "Filter Members Now" button.

Now, JangoMail is prepared to send to half of your JangoMail Group.

After you send this e-mail, you may want to send a varying version to part "B" fo your Group. This step is very simple. This time you will NOT start in the "Filter and Send" section. Just go to the "Send E-mail" section, elect to send the e-mail to the entire Group in the Group selection box, but then down below, under "Don't send to recipients of these past e-mailings:", choose the e-mailing that you previously sent to part "A" of your Group.

This will filter out everyone that received e-mailing "A", thereby sending to only the second half of your Group.

Using an External Database Connection

If you are using JangoMail to pull in e-mail recipient data in real-time from an external database, then you need only write the appropriate SQL query to pull in only half of your records. For example, if your e-mail recipient data is stored in the table "Contacts", the SQL query would be:


If your database does not support the "percent" designation with the TOP keyword, then you can manually specify the half-count of your table. If your table has 5,000 records in it, you could use:

SELECT TOP 2500 * FROM Contacts

Bug Fix: Large Group Email Lists Display Faster Now

In the past, customers having a large number of e-mail addresses in a Group (over 1 million) may have experienced long delays when in the "Groups and E-mail Addresses" section, after having selected the Group and waiting for the list of e-mail addresses to display in the blue area.

The list of e-mail addresses will now display much faster. Additionally, sorting through the list 200 at a time with the <> links will now operate much faster. And lastly, using the Search box to find an e-mail address or a range of addresses will operate much faster as well.

HTML Editor Upgrade / New "Send E-mail" Features

We have upgraded our Enhanced, Java-based HTML editor. We have also enhanced the look/feel/functionality of the "Send E-mail" page. If you use the Enhanced Editor (as opposed to the Simple Editor), the following changes are now in effect in the editor:

1. The "Insert Images" dialog box has a better and faster user interface. Firefox users previously were unable to insert images using the Enhanced Editor, but now this has been fixed.

2. There is now an "Upload Images" button to the immediate left of the "Insert Images" button.

3. Some users were experiencing an issue where the spell-check feature would not work. This has been resolved, and spell-check should now work for ALL users.

4. The font and heading dropdowns now contain the options in the actual fonts and headings that are available.

5. There is now a "Print" option under the "File" menu.

6. Composing a plain text version of your HTML message is now as simple as clicking a button. Click the "Set Plain Text Automatically" button next to the Plain Text field, and JangoMail will automatically generate a plain text message based off your HTML message in the Enhanced Editor.

7. The "personalization" instructions above the Subject/Message area can now be expanded/collapsed at will, which gives the page a much cleaner and efficient look.

8. You can now decide whether the Plain Text or the HTML Editor loads when you first go to the "Send E-mail" page. You can configure this option under My Options --> User Preferences --> Send E-mail Page.
