SMTP may limit the number of emails you can send each day

Every outgoing SMTP mail server is guided by a provider’s email policy which includes hourly and/or daily email send limits. This policy will ultimately determine how many emails you can send each day. You can find a list of the hourly and daily send limits for most of the major ISPs, web hosting companies and Free email address providers below.

If you try to send more email than the hourly or daily email sending limits of your mail server, you will notice errors being returned after the specified quota is met, saying something along the lines of:

you have reached your daily sending quota…

If you surpass the daily SMTP email sending limits of your provider, you will generally have to wait 24 hours before you can send more email through that particular server.

What can you do if your mail server has limits that don’t support the size of your mailing list?

If your current outgoing SMTP email server does not support your email list size or sending frequency, you have a variety of options:

1. Contact the host of your outgoing SMTP mail server(s) and ask if they have a business account that lets you send more emails each day to support your business.

2. Find a web hosting company who has daily email sending limits that meet your needs.

3. Setup your own MS Exchange Server and configure it for SMTP email delivery.

4. Instead of sending through the system, run your campaigns and select the export option to send through a third-party. Some options are: MailChimp, VirticalResponse and ConstantContact.

So, while ServiceMonster allows you to send and manage email lists of an unlimited size; the success of email delivery to large groups is ultimately dependent upon the sending limits set forth in the email sending policy of the SMTP mail server you are using.
