Multi-Threading
Gammadyne Mailer has the ability to send up to 1024 emails simultaneously. This feature is known as "multi-threading" or "multi-tasking", and can greatly increase the speed of the send operation.
When sending an email, a lot of time is spent waiting for a response from the mail server. Multi-threading allows Gammadyne Mailer to keep working on another email while waiting for the response. The improvement in throughput is huge. Multi-threading allows virtually all available upstream bandwidth to be utilized.

Configuration
Configuration of Multi-Threading is quite easy. On Gammadyne Mailer's "Send" branch, locate the "Threads" field and enter any number between 1 and 1024. When sending email through an intermediate SMTP server, 4-10 threads are recommended. When performing a Direct Delivery, 15-35 threads are recommended.
We do recommend enabling the Universal Domain Throttle because flooding a mail server is likely to get your email blocked or could even result in blacklisting.
Some mail servers have a simultaneous connection limit. If you experience "Unable to connect to server" errors, try lowering the number of threads.
