@Ian_s When you reply to @Fuellemann above, if you’re not using Form Pro you might want to. Your host may require that you use SMTP for sending your form emails. This is a feature Form Pro has.
Hi Fuelleman,
I am using the form stack, when user presses send, they get a message saying ‘Sorry there was an error sending your message. Please try later’
Has been working fine but suddenly stopped, or client has only just realised!
