If you use a solid host like WPengine and a security app like wordfence.com it would be a very rare day indeed to get hacked. Source: about 1 year ago
If on wordpress, use the free version of wordfence.com to scan your site and identify possible viruses. Continue to use wordfence to protect the site, and if a successful business blossoms, consider the premium paid version. I'm not affiliated in any way, I've simply used the product with success for a number of years. Source: about 2 years ago

If you're not getting the right email addresses from ContactOut and it's bouncing back, you could always run the email addresses through something like emaillistverify.com to make sure they're valid before you try to email them. (you should do that always anyway to protect your email deliverability). Source: almost 2 years ago
