How many emails can SMTPSWITCHMAILER send per hour?
>>This depends greatly on your mail server specifications.When you send out your mailing using SMTPSwitchmailer, you need an external SMTP server. SMTPSwitchmailer connects to the SMTP server and relays the message; any port can be used, as long as the SMTP server can listen on that port. The SMTP server itself will then deliver the message. When using the third party SMTP servers, your sending speed will depend entirely on the SMTP server’s speed.
