Topic: Recipient lists limited to 50?

I have a recipient list file with 51 email addresses in it.  When I create an event and insert the list file name as the send to, no messages are sent.  If I remove one address from the file, the messages are sent.

Is there a limit of 50 addresses in a recipient file?  If so, can I use two file names and limit each file to no more than 50 addresses?

Re: Recipient lists limited to 50?

Hi there,

In the LuxCal calendar thee is no limit to the number of recipients in the list, however, emails to the recipients of your list are send in one go and many (probably all) internet providers have set a limit, to avoid their customers to send spam. So I think your limit of 50 is set by your internet provider.
Using two files each with for instance 49 recipients will not help, because LuxCal will process both list before sending the emails.
If you really need to send emails to more than 50 recipients, you should use SMTP mail, or ask your provider to increase the limit of 50 emails.

Re: Recipient lists limited to 50?

I am using SMTP to send the reminders.

I verified with my ISP that they do limit an email to 50 addresses when sent. They also limit each account to 250 emails per hours. Neither limit can be raised while on a shared environment.

So here come the questions (sorry, I just try to be thorough):

Is there a setting in the program to get me around the limit my ISP imposes?

Is there a way to have the program send out the message in blocks of ten or twenty, thereby overcoming the ISP limit of 50 per email?

Could I set up the same calendar entry twice but only have one of them visible to the group?

Thanks for your help, as always,

Bill

Hi Bill,

Currently there is no way to send emails in blocks.
But I'm willing to experiment with this and change the code so that emails are send in blocks of maximum X recipients. (X to be specified).
In this case you would be kind of a guinea pig.
If you are interested, I suggest you send me your email address (via the Contact Us page) and I will modify the code and send you an updated messaging.php file.

Re: Recipient lists limited to 50?

Hi Roel,

As already mentioned pretty much any ISP limits the number of emails either at one sending, during an hour or perhaps even during a 24 hour periode. For most small sites the limits aren't an issue. I have seen different programs / scripts that allow the number to be set in the settings of how many to send in a given periode etc.

The one main site that I have a customer running LuxCal on has 380 members. They aren't in LuxCal so it will never be an issue as far as LuxCal goes for them but might be if they were and there is a 250 limit.

That is why many sites etc have gone to using a site / service like Mail Chimp. There is also an integration feature which may or may not also be a possibility with LuxCal. https://mailchimp.com/integrations/

Re: Recipient lists limited to 50?

Hi Dan,

Good to now about your customer. I think it's not very difficult to send emails in batches of a certain number. Bill has contacted me by email and is offering to help me testing this. Of course once it's working to our satisfaction I will make this available in the next LuxCal calendar release.

Cheers,
Roel
