Have you ever lost your website, the one you had spent a lot of effort and money on, because you did not renew your domain and/or hosting?
Domain is usually extended every year, although there are options when domains are bought for several years ahead. Hosting can be extended monthly, semi-annually, annually, etc.

In most cases, your domain name registrars send you e-mail notification that your domain registration period is over and it should be extended. One can say not to worry about it. But what if the e-mail address, used in domain registration process was deleted or forgotten? Or, perhaps, your ex-administrator or ex-contractor registered domain using his name and e-mail, and you no longer work with them? And what if the notification letter got into the Spam folder in your mail box, and you did not read it?
There are many varieties, so it's better to play it safe and use Dominder for extra reminders of domain and hosting expiration.
In contrast to domain name registrars, Dominder is able to send as e-mail letters but also sms-messages to an unlimited number of recipients, which reduces the chance of losing the site to a zero. It is also possible to set two dates of sending notifications: for example, 20 days and 5 days prior to the domain expiration.
Ensure yourself and your business, use Dominder to monitor your sites.
