You will find that not many people will help because of the lack of code. Just always make sure that when you ask a question like this wondering why something isn't working, you provide code so people can pin point a problem. Stack Overflow don't put that page there before you ask a question because they think you're stupid, they do it so you can get a more specific and the best response to your question. So just make sure you give this a look.
However, I had a similar issue before where all my mails were being sent to the spam folder and they're a few things that could be the cause:
Mail Client Reverse DNS Checks: You mentioned that you are using a personal domain but one thing to remember is that your domain will have its on DNS server.e.g. if you are with GoDaddy that would be the default DNS setting. So the problem is that when you send an email to lets say a #outlook.com email server the mail client of the recipient will do a reverse DNS check. So it realises that you are sending to an #outlook.com but the email is coming from #letsupload.co. So it realises that you are sending from an IP that isn't related to the domain you sending to and that is what SPAM is! Like I said without seeing your code I can't exactly know how to help but if you aren't aready using a mail server with Authentication enabled that could be a cause. Try using a server with authentication and add this code:
// I am using $mail as my instance of PHPMailer
$mail->Host = 'your-new-server-with-authentication';
$mail->Port = 587; // usually the default port (double check though)
$mail->SMTPAuth = true;
// now define the username and password for your mail server
$mail->Username = 'your-username#mailserver.com';
$mail->Password = 'OpenSesame123';
Reply to: You can also try adding a reply-to email address. Some mail servers tend to put emails in spam that don't have a reply email address to stop bots from spamming a person's email account. So try adding this if you haven't already:
// I am using $mail as my instance of the PHPMailer
$mail->AddReplyTo('youremail#domain.com');
Implementing SPF: If the above to fail then the chances are that you need to implement SPF. You can learn all about this from an expert on the subject gr8gonzo here is the tutorial and article he wrote on the subject. That will not only just help with implementing SPF but also with the best practises for when you're sending emails.
