Email Batch Sizes

You should not run into size issues when sending invites to research activities, however during community member recruiting or some other email list invited activities you may reach out to a large number of people. 

To make sure you community does not experience sudden activity spikes that might degrade the user experience and lowering the quality of responses you receive.  In other words, you get better data and happier members if you keep the load lighter.

Please follow these guidelines for sending successful mass mailings containing links pointed to your community website or a survey on your community:

• Limit mailings to 100,000 or less  email addresses at a time
• Space mailings at least one hour apart
• Inform your account manager when a mass mailing (50,000 emails or more) will happen
