summary

rob_updates.pl is my home grown solution to list management. Generally, it should not be preferred over many other fine opensource list managers, except for one detail: automatic name removal.

Automatic Email Address Removal

For each email address in the list, there is a date field, which defaults to 1 year after the name was added to the list. After the email address has been on the list for a year, the next email sent to that address will be The Last Email, and a note attached informing the user they must reply and request to remain on the list.

If they do not reply, they will not receive any more emails.

If they do reply, the human admin for the list can decide how much longer to leave the name on the list. Options are adjustable, but something like, 1 year, 2 years, 5 years, 10 years, 15 years, 100 years.

faux-technical explanation of automatic email removal

In the DB, the recipients have the above mentioned date, and a "color" associated with their name:

Green = they will receive the next email Yellow = automatic-removal warning has been sent to the address Red = they did not reply to warning, or they explicitly requested removal (so do not send another message)

When an email is sent:

  • If the address is yellow, change to red and do not send.
  • If the address is green, check their automatic removal date:
    • If the date is in the future, send the message
    • if the date is past, change them to yellow and send a warning along with the message

Known Bugs/features

  1. Email list names cannot have spaces
  2. If an address is added but already exists in the list, the dbi error isn't caught properly. This used to work, but I think something changed with DBI
    • look for "1" to find the bug area in the source below

Source Code

<source lang="perl">

  1. !/usr/bin/perl -w
  1. rob_updates.pl sends one email per address to a mySQL list of emails
  2. v 0.5 read db login info from a file
  3. It allows users to opt-out with two clicks. It doesn't
  4. keep track of bounces. It doesn't allow opt-ins (thereby
  5. sidestepping the issue of forged emails, etc). It archives the
  6. emails on my site.

  1. -------------------------------------------------------------
  2. -
  3. - the basic idea I have in my brain here is to allow automation of cleansing the list.
  4. -
  5. - adding three date fields to the database:
  6. - added  : the date the record was added
  7. - removed  : the date the record was dropped
  8. - keep_through  : the minimum date before asking if they should be removed
  9. -
  10. - adding a status field with three possible values:
  11. - [green | yellow | red]
  12. -
  13. - From now on, I will not actualy remove names from the list. The code will check their status to see if they get an email or not.
  14. -
  15. - For each record:
  16. - When adding a new record: update 'added' field
  17. -
  18. - When sending an email:
  19. - If red, do not send.
  20. - If yellow, change to red, update 'removed' field, and do not send.
  21. - If green, check keep_through.
  22. - If today > keep_through
  23. - change to yellow
  24. - tag the message (let me know if you wanna stay on the list)
  25. - send the message
  26. - else
  27. - send the message
  28. - end if green
  29. -
  30. - When doing any other processing, if remove is requested, change to red, update 'removed' field
  31. -
  32. - When I get a request for extension, I manually boost their keep_through date.
  33. -
  34. - This system is contingent on the cycle of emails being sent being
  35. - less than the expected cycle that users will check their email
  36. - and respond to a query if they want to extend. If I send out too
  37. - quickly, they will not have time to respond.
  38. -
  39. - Because I check my email more often than the average bear, I will
  40. - allow an easy mechanism for me to change their status, in case
  41. - they went red and wanna come back.
  42. -
  43. - I want to write some nice AJAX style tags to edit the fields on the View Names screen
  44. -

   # Above, we have calculated everything we need to know for writing

   # explains the filenames being used.  The basic idea is to write
   # the updates in two places: in my journal, and in my 'travel'
   # directory.  Indexing for the journal is done with its own mechanism,
   # so we don't need to worry about it.  The indexing for the rest
   # of my site has been done by hand (until now) by updating the
   # file /home/thunderrabbit/setup_journal/navigation_definitions.txt.
   # Keeping that updated fell to the wayside; I would send out Rob
   # Updates, but never update that file, nor even write these to the
   # appropriate directory.

    1. &critical_settings_check is supposed to make sure the system is fit for use whatsoever.
    2. Basically:
    3. We must be able to read the settings files into hashes
    4. We must be able to access the database
    5. If NO to any of the above, it's a critical failure from which this program cannot recover.
    6. But, try to fail gracefully; errors here will most likely fail during initial setup,
    7. so the user (admin) should be given an idea of which file didn't exist or had a problem, etc..
    8. &hash_read and &DBConnect will throw errors if they fail.

sub critical_settings_check {

   # this is the root of all settings in this project

   }
   &hash_read(\%dbHash,$settings{'dbHash file'});
   # Make sure we can get to the database.
   $dbh = &DBConnect(%dbHash);

} # &critical_settings_check

    1. We have come to a problem that cannot be resolved by this script.
    2. Exit and display hopefully useful information.
