There are several contributors that can factor into why an email may be delayed. It is most likely directly related to the size of the recipient list as it can take some time to send to a larger list.
The internet connection speed also plays a big part in email deliverability speed.
If you or your guests haven't received an email from Splash on time, it's possible there is a slight delay in delivery from our email processor. If you notice a delay exceeding an hour, please reach out to us and we'll investigate.
Don't forget that you can view who has received and opened your Splash emails right within the Email Sender!
