Our website crashed because many people came to our website for pre-registration.

Hence, we understood the demand of people and increased our server capacity quickly.

Now, our registration is being started and I’d ask you to register any of the courses that are relevant to you on the next page.

As I’m writing this email, many people have already taken the course. And now, we have very few spots left in our hands.

P.S. Still, you have the last chance to access it. So, don’t procrastinate now, and take action quickly.
