How many messages does it send per hour?
Not MailList Controller defines the speed, its the environment. The message speed depends on the internet connection (upload speed), the connection to your mail server, the mail server performance and the size of the message.
- A DSL connection has a speed of 2048/256 kbit/s
this means the upload speed is 256 kbit/s, which equals 256 kbit/s /8 = 32 kbyts/s
If the message has a size of 32 kbyte, then you can send (theoretically) 1 message with a size of 32 kbyte per second
- Upload speed: 512 kbit/s = 64 kbyts/s
- Upload speed: 1024 kbit/s = 124 kbyte/s
If you have a mail server in your local network, then the speed is very high and you can send a large number of messages within a short time. In some cases it could be required to slow down or limit the speed. MaillList Controller has an option to slow down the mailing or limit the max. number of messages per hour.
Some anti-virus programs, which have an option to "scan outgoing messages" have problems with a larger amount of messages and can slow down the mailing speed.
The program can not send more messages as your mail server or mail account allows. Some mail accounts have limits, e.g. some allow to send only x messages per hour. Please use the "List Settings -> Outgoing Mail Server (SMTP) -> Limit" feature to adjust the program to such a limit.
Mail Server Pickup Folder for Direct Mail:
This option can be used if you are running a local mail server, which has a pickup folder. In this mode, the program does not use SMTP. It creates an .eml file in the pickup folder for each message, which will be picked up by your mail server. MailList Controller will create the messages in the pickup folder very fast: up to 100.000 messages in less than 5 minutes, so it might be required to slow down or limit the number of messages per hour, if your server runs out of resources. This option is the fastest way to send mailings if you are running a local mail server, which has a pickup directory. Please note, that the program does not receive any confirmation from your mail server and your mail server is responsible for the mailing an error processing. Please refer to the user manual of your mail server for further details.
