A website does not make money. A chain of five connections makes money, and the website is only the first link. Every one of those joins can break without telling you, which is why so many people have a site they are quietly disappointed by.
Here are the five, in order, with how to test each one.
Someone fills in your opt in form. Does a contact actually appear?
This fails more often than you would think. A required field hidden by your own styling will block submission with no error at all: no request goes out, nothing happens, the visitor clicks twice and leaves. Repeated testing can also hit rate limits, so a form that worked yesterday appears broken today.
Test it: submit the form from your phone, on mobile data, with an email address you have never used before. Then go and find that contact in your platform. If it is not there, nothing after this point matters.
A tag is how your system knows which thing this person asked for. Without one, every subscriber is identical, and identical subscribers get identical emails, which is how people end up being sold something they already bought.
Test it: open the contact record you just created. The tag should be on it. Not a similar tag. That one.
The tag should trigger the sequence. This is where the silent failures live, because a rule can sit there marked active, looking perfectly healthy, and have never fired once.
The most common cause is not the rule at all. It is that nothing is granting the tag, so the trigger never happens. The second most common is that the rule was created in a mode that never matches the form it is supposed to watch.
Test it: do not look at the rule. Look at the rule's history. Did it fire, for your test contact, at the time you submitted? If there is no history entry, it did not run, whatever the status badge says.
Someone pays. Do they receive the thing?
The usual cause of "I paid and got nothing" is not the email and not the automation. It is that the product grants nothing, so the delivery rule never had a reason to fire. The rule is fine. It is waiting for a signal that never comes.
Test it: buy your own product with a real card and refund yourself afterwards. Test mode does not exercise the part that breaks. Then check all four: the order appears, the buyer record carries the right tag, the email arrives, and the link inside it opens the right thing from a logged out browser. That last one catches files shared to the wrong audience, which look perfect to whoever set them up and fail for everybody else.
They have the thing. What happens on day three?
This is the join most people never build at all. The download lands, the sequence ends, and the person who raised their hand hears nothing else from you. Nothing is broken. There is simply nothing there.
Test it: look at your own sequence and count the emails. If it is one, that is the gap.
All five of these joins are dropdowns rather than integrations when the site, funnel, emails and checkout live in one account. Mine are on Systeme.io, and the free plan builds the lot. Open a free account here. Affiliate link, so I earn a commission if you later go paid.
Confirm the outcome, never the click. A success message tells you the button worked, not that the thing happened. Go and look at the live page, the real inbox, the actual contact record.
Every one of these failures is invisible from the dashboard and obvious the moment you test as a stranger. That is the whole job.
Confirm the outcome, never the click.
Checking five joins properly takes a couple of hours and knowing where each one hides. It is not a big project. It is usually the difference between a site that looks finished and one that actually works.
