I’m on the free plan, what does “Throttled” mean?
Customers on the free plan have emails sent at a slower rate. This rate varies depending on our system resources at the time — it’s typically around one email sent (deliverable) per minute. In other words, an email sent to 60 subscribers would take 60 minutes to deliver.
If you want immediate sending to all your subscribers, buy the lifetime plan.
You can send emails to your subscribers at a faster rate, and it also gives you additional features like reduced SendFox branding.
