You might also want to check with your email & internet providers.I have checked the spam filter. Elio motors is not tagged
We've had it happen before that they will blacklist / block mail from some; if they use keyword blocking it could be that the keyword they used has a part of an Elio address. Explain what's going on first and be detailed with them, plus include that you have already checked your system first, they will ask.
Then ask them if they've blocked the following: eliomotors.com, wordpress.com, eliomotors.zendesk.com, or anything else with elio in it.
Then ask them if they could make sure to whitelist those addresses for you.
Depending on your provider, they should be willing to work with you.
