When you sign up for an internet service, the provider will hook you up with an email address, too. Your internet service provider (ISP) wants to keep you connected to them. But this convenient email address isn’t always the best long-term solution for you. That “[email protected]” email address may work fine. You use it to keep in touch with your family and friends, you get bills to that address, and you’ve used it to log in to your social media and online news and shopping sites. But relying on your ISP for your email address may not be the best strategy for you. Here are some drawbacks to consider.
You’re Locked Into Their Service

If you rely on your @isprovider.com address, you could end up locked in with poor service or high prices. You feel stuck because you can’t take your email address with you if you want to switch providers.

Email Services May Be Outdated

Internet service providers are not in the email business, whereas email providers such as Gmail and Outlook are always working to improve. Your ISP may not have updated its email offerings for a decade and you may be missing out of features that make managing your Inbox more convenient.

Lower Storage Limits

Most ISPs have very limited storage space for email, which can make your service less reliable and convenient. Google’s Gmail for example, comes with 15GB which is more than adequate for the vast majority of home and small business customers.

Less Spam Filtering Options

Internet providers generally do not make the same effort to keep your email secure and your inbox spam-free. A provider more focused on email services offers more sophisticated filtering. ISP emails usually have primitive spam filtering based on keyword detection that is easier to bypass
May Be Harder To Access

With an ISP email, your email is often accessible only on the provider’s mail servers, and you need to be able to access those servers to get to your emails. A cloud-based email provider lets you access your inbox via a Web browser meaning no matter where in the world you are, you can still get access.
You May Lose If Their Business Closes

Many customers choose to avoid larger service providers such as Telstra and Optus to support a small business. While they may offer a more personalised level of service and competitive pricing, if they ever go belly up, your email address may be lost for good.
An Important Note

There is, however, one major advantage of having your email address with your Internet service provider. That is your ability to get support if you ever forget your password, find yourself hacked, or if your account is accidentally deleted. While you can get this level of service with most paid providers, if something goes wrong with a free Gmail, Hotmail, Outlook, or similar account, you may be locked out for good. That’s why it is vital that if you use these free services you make sure your security information is always kept current and use two-factor authentication when possible.
