Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

    email_send2 with 150+ letters.

    Just wondering if anyone has used email_send2() in a loop to send over 150 *separate* letters with a different pdf file (invoice) attached to each one. (It could be up to 500 eventually.)

    I'm just looking for confirmation that it should work fine and not trip over itself with that many letters before I give it to a customer.

    I've tested it with 5 different addresses and it works fine. I'm just hoping to avoid the difficulties of creating so many different e-mails simply for testing. Especially since I don't know if/what limit there might be.

    I'm also curious if I should expect to run into problems with the ISP when sending so many one after another. Might they think it was a spamming attempt?

    Note that this is NOT one letter sent to 150+ e-mails. It's 150+ separate e-mails to different people with a different invoice attached to each letter. The loop does not pause between each letter; it simply creates the new invoice pdf, builds the new e-mail with the pdf attached, and sends it. The only "pauses" in the loop are whatever is "built into" (or "resulting from") the Report.Save_as() and the Email_send2() functions.

    WHY DON'T YOU SEND IT TO YOURSELF FOR TESTING PURPOSES.

      Because, to test it properly I also need to build all those unique PDF documents to go along with each e-mail so I can test that also - just in case it has an effect. There's also the possibility that sending 500 e-mails to the same address is not the same as sending 500 e-mails to 500 different addresses.

      It can be done but I was simply hoping someone else had already done it in real life and could save me the effort. If I test it myself (rather than letting a customer test it - which may happen), I would probably do 500 which means I would want to set up 500 e-mail addresses on my own website (or maybe 50 and loop through them 10 times - but, that might also create a different situation) and that might take awhile. I'd also have to add all those "new customers" to the database and modify the routine to build a new pdf document for each e-mail since the "new customers" wouldn't have invoices yet. Of course, I could add new invoices but that takes time too.

      Rather than spending a day or two entering data and modifying routines, I was hoping someone else had already been through it.

      By the way, I've already sent it to myself in groups of 5 many times.

        Cal,

        I have sent emails with an attachment to 1500 individual addresses. You may find issues with your ISP anti-spam settings.

        Fortunately I was doing this on a small local ISP. Had to have them let me use a non-authenticated smtp server. It was not for public use, but the only way to not get shut down.

          I did this for a while Cal, and it'll work but gets kinda slow and you risk the server session timing out, etc. This is a billing system for a national company.

          What I decided to do instead is make their data available online, with each user being able to login through the user portal, etc. They can choose to view any month's bill while online, presented as a PDF.

          I still send emails -- currently about 200 -- each month to notify them that their latest bill is available for viewing at their online account. My server's at FirmSupport, as is my email account, and they turned a couple knobs to make sure their system wouldn't block this up as spam.

            Cal,

            I can't speak for all ISP's, But I have sent about 126,000 emails in a loop. Using RoadRunner, you have to time for 2 hours every 49 emails. This stays under their radar(so to speak). I also found I needed about a second between emails for it all to clear before the next one was sent.

            YES, I was spamming.
