There might be different reasons as to why you stopped receiving emails from us:
1) You have unsubscribed. If you unsubscribe from our promotional emails it stops you from receiving any other additional emails from us, such as lectures, for example.
2) You deleted one of our emails from your spam folder. This automatically marks our emails as SPAM in your inbox and you won’t be able to receive any further course lectures from us.
3) Your inbox was disabled, full, or had another problem alike - resulting in one of our emails bouncing. In this case, you stop receiving any further course lectures until you contact us and the problem gets solved.
4) You might be impatient or just eager to learn. Almost every lecture says when the next one will be sent. If you don’t receive the next letter in the time promised, please note that the letters can be delayed by up to 24 hours in consequence to differences in time-zones.
Solution
Reply (Don't send a separate email) to the last lecture you received and we can look further into the problem.
