Письмо от SaaS сервиса

Написал текстовку письма для сервиса, у которого 13300 пользователей.

Сервис был бесплатным, но пришло время монетизироваться.

Hey Kirill,

I thank you for choosing DM and supporting us with your time and dedication. I am writing to let you know that there are some pricing changes to the product’s subscription.

We had to review our pricing strategy due to to the expansion of our development staff and support. 

We now have 13,300+ users and that's fantastic, and we get a lot of requests for new features and support.
I want to make sure that DM is always as useful and efficient as possible – it is my first priority at the moment.

To make this happen, we had to set the subscription fees (right now DM is free).
We'll keep the free plan, but with limited features.

BUT - I think it's only fair to give you a good deal and offer you a 50% discount FOR LIFE. All you have to do is respond to this email and let me know so I can take care of everything for you.

Thank you so much for your support throughout the year. Our new prices will allow us to better serve you and our future customers. If you have any questions, please don’t hesitate to ask, I'm here to help.

Cheers,
DM's CEO
