Transfer the domains over to a better more secure registrar. Then set up a server or vps and set up as many mailboxes or emails that you need.

Using bundled services from your domain registrar is especially problematic though, because when you switch registrars, you usually lose those bundled services, even though you already paid for them. Often, there's similar services available at the new registrar, but there's a cost to switch, and it's much more difficult to switch because the service provisioning is often tied to the domain process; service at registrar B won't be online until the domain is moved, and service at registrar A may be turned off immediately after the domain is moved, so you have no way to make an orderly transition.
The point is that a single vendor for everything can ruin your life.
Having a good plan for scaling is absolutely a great move. Changing fundamental architecture later isn't easy. Implementing it all immediately however ..
The problem is that most domain registrars won't help get your domain name back. Many domains are stolen because they hacked the email address and not the domain registrar account (even though that's how they got access). Most domain registrars don't care at all, and won't help. And there are no current ICANN policies for dealing with stolen domain names. Even UDRP is not set up for dealing with stolen domains. Although we were successful getting one back via UDRP since the business was using the domain previously and we ended up claiming 'commonlaw trademark'.
This is one reason why we've been so successful getting stolen domain names back for clients: we use some alternative methods, such as actually talking to people at the registrars involved and talking with the domain thief, to get domains back.
Don't leave us hanging like that! Which are the registrars that do care, and will help then? Even if they cost more.
registrar or DNS gets hacked -> attacker can receive mail as you (by transferring your domain or changing your MX record)
e-mail host gets hacked -> attacker can download your inbox
both -> both
