This is most often an upstream issue unrelated to WS Form itself. That error messages suggests that the wp_mail hookable function in the Postmark plugin failed. Unfortunately I don’t think the Postmark add-on sets an error message therefore we are unable to capture it.
I’d recommend checking that your To address is correct. We’ve also had reports that the Postmark add-on doesn’t like characters such as & in the display name. You could try setting the To address to be only the email address and not a display name.
Also ensure your From address is from a domain that has been validated in Postmark. You can learn more about setting up Postmark with WordPress here:

Thanks!
Thanks for the reply, Mark. I was able to get the emails sending by swapping the ampersand out of the site title with the word “and.” Good to know!
Hi again Mark, not sure how much back and forth you do here, but I’m still having issues.
It seems that the notifications will only send to the site admin. Here’s a screenshot of the notification email settings. The recipient is not the site admin, but the business owner:

I’ve also setup an email to send to the prospect after form completion, but these don’t send off at all. Screenshot of setup:

Do you think there is some other conflict going on here? Or could there me some misconfiguration within the plugin?
Thanks kindly!
We send emails via the standard wp_mail pluggable function in WordPress. Postmark plugs into that and is responsible for email delivery thereafter.
I would recommend checking that your Postmark account is set up correctly and that the From address you are using is fully validated with Postmark. Also double check that field ID 3 is your email address and field ID 1 is the display name you want to use.
We have seen issues where some SMTP plugins are not fully RFC 2822 compliant, which wp_mail requires. In which case, try only setting the email address and leave the Display Name settings empty.
We have some more information here:

If issues persist I’d recommend reaching out to Postmark for support as they will be able to confirm your account is set up properly.
Thanks!
