There can be many different reasons why you are unable to send emails. Below mentioned are a few steps to narrow down what might have happened to an outgoing message.
The email client used to send an email.
If you are facing an outgoing email issue on an email client, we propose you send a test email from Titan. If you can successfully send a message there but not from a local mail client, you may verify the specified SMTP settings.
Also, ensure that your computer is connected to the Internet and the client is not offline.
Bounce back email.
Do you receive any bounce-back email on sending an email or an error pop-up is displayed? If so, see common email bounce-back article for possible solutions.
Email marked as spam.
Verify with the recipient that your message was not marked as spam. If your message was marked as spam, learn how to avoid having your emails flagged as spam to counter this in the future.
Sender Policy Framework (SPF) records are used to prevent any mail forgery, email spoofing, etc. by verifying whether the sender is genuine or not.
Please ensure that an SPF record is present on your domain and points to the following Titan Mail record -
TXT value: "v=spf1 include:spf.titan.email ~all"
