I need to send survey out to 1500+ email addresses. is that possible through Survey Gizmo?
You can definitely send to 1500+ email addresses. If you want to send all at once, you can start here, or if you’re trying to email every time they complete a survey, you can find that information here.
Note that in my experience, the SG email service is not always 100% on-time. There have been times when I have set up the post-survey email to send at X minutes past completion, and it has been inaccurately sent hours later. If you’re super concerned about this happening or it will affect your data/output, I would recommend just using a service like MailChimp.
