hate to beat the drum (disclaimer: I run marketing for titanx) but we do guarantee tripling your connect rates in our paid pilot or your money back + $10K
we exist to solve this problem, if you'd like to read more POV stuff on it, I'm typing the below fresh by hand:
Connect rates have been in decline for the last decade or so. It started with outbound calling funding by Growth-at-all-Costs outbound teams, then accelerated vastly when Koncert and Orum came on the scene with parallel dialing. This worked for a few years but also precipitated its own friction, as call volumes increased, telcos marked more numbers as spam, and most numbers you can now get via Twilio API (which is what most dialers rely on) are well on their way to being marked as spam likely by at least one carrier anyway.
iOS26 hurt a bit, but in our data it still accounts for less than 2% of all recipients (since it needs to be turned on manually). This may change over time, but even as it does, it helps to use phone intent (TitanX) to score these numbers before you call them to identify which are likely to answer.
