Even more awesome LotusScript mail merge for Lotus Notes + Microsoft Excel

UPDATE: May 20, 2011 – David Turner has shared his excellent improvements. Check them out!

UPDATE: May 28, 2010 – fixed errors caused by default Option Declare. Thanks to Lisa Harnett for the feedback!
UPDATE: Oct 19, 2010 – fixed Quit(). Thanks to Vance for the feedback! Also, clarified tokens.

Based on the feedback on my Lotus Notes mail merge from a Microsoft Excel spreadsheet (2009), I’ve refined my merge script to make it more awesome. How is it more awesome?

  • Prompts you for drafting or sending
  • Saves sent messages
  • Allows you to customize the subject
  • Uses [ ] instead of < and > for built-in tokens ([to], [cc], [subject]) for less HTML confusion in blog posts and replies
  • Displays number of sent messages and errors
  • Closes the Microsoft Excel spreadsheet afterwards

The search-and-replace tokens are defined in the first row of your Microsoft Excel spreadsheet. The script searches for them in the message body, replaces them with the appropriate values from the current row, and either saves the message as the draft or sends the message. There are a few built-in tokens for this script ([to], [cc], [subject]) – these are case-sensitive, so enter them exactly like that. All the other tokens are up to you, so you could use FOO and BAR as search-and-replace tokens if you want.

Tokens are replaced only in the message body. If you want a variable subject line, use a formula to calculate the subject in a column with the [subject] header.

As always, test your mail merges with a small list before using it for your entire list. Create an agent and call it something like “Mail merge”. Edit the agent and set the type to LotusScript. In the (Declarations) section, add

%Include "lsconst.lss"

In the “Initialize” section, put in:
