SendWILL Popup Email Marketing

Absolute catastrophy.
went well until I tried to switch automation from Email and flow to Trustoo.
Has blocked all my workflow, takes ages to personalize a mail as it is super slow.
They have blocked all my flows because they wanted me to clean my bounced contacts (280 contacts).
Now everything is blocked. Customers cannot do any newsletter subscription anymore as no automation runs and customer support isn't available to fix things before 24-48h.
That is so much potential orders lost.
Just don't try
