Learn English – pronounce a “t” as a glottal stop in the word “Netflix”

To preface my response: I'd prefer to leave this as a comment, but since my reputation is less than 50, I have to post it as an answer, as I do not have the ability to comment until I've acquired additional points. That being said, it definitely is not a complete answer by any means.

As the prior comments state, the pronunciation varies by region. I'm originally from Minnesota, where we're known for prolonged vowel sounds, particularly when a word contains an "o". Yet many call centers open here as a result of our accent being perceived as one of the most neutral and easy to understand in the country. Which I only mention as a means of highlighting how ambiguous the concept of "correct pronunciation" is in the U.S.

That being said, at least in the portion of the Midwest I'm from, it's pronounced like "bad" + "mitten".

There is variation among English speakers. I'll give you my ordinary pronunciations, which are not unusual for a Midwesterner.

It would be nice to meet her.

The "t" of "It" is a glottal stop. The "t" of "meet" is a flap. "meet her" sounds like "meter".

I've got you.

There are two possibilities: the "t" can remain if the "y" is pronounced "sh". Or, the "t" can be a glottal stop if the "y" is unchanged.

Right now.

The "t" is a glottal stop.

For the pronunciations with glottal stop for "t", it is also possible in a slower more deliberate style of speech to use a glottalized "t", which is the same as glottal stop except with the tip of the tongue touching the alveolar ridge (as it would for an ordinary "t"). I think this is what you are describing in your question.
