For people running outbound: what works, the rules, and the math behind decisions.
Apple is shipping a Messages update this fall that rewrites three things a sales team measures without touching a single thing a sales team does. Reactions stop being text. Suggested replies start sounding like the person sending them. Failed sends retry without telling anyone. None of that is a feature announcement for outbound, and all of it lands in your numbers.

iMessage outreach
OpenAI's Apple Messages plugin can read your message history and send a text as you, on one Mac, with an approval tap per message. Sales teams are asking whether that replaces an outreach platform. The answer sits in OpenAI's own documentation and usage policies rather than in anybody's opinion.
Setup promises in this category run from 15 minutes to about two days, and one provider will not allow an outbound first message at all until a separate gate clears. Each vendor is timing a different step, which is why a launch date built on the number in the hero slips.
Buyers compare the monthly price of a line and then build the campaign. The constraint that stops the campaign is somewhere else: a new-conversations-per-day figure buried in a comparison table, and an acceptable use policy that names cold outreach as prohibited on every plan. Both are published. Neither is on the page you compared.
Your first text to someone who has never messaged you back is not the same object as every message after it. On iPhone the link inside it will not open. On carrier SMS the same link is one of the strongest reasons a message gets filtered before it lands. Both problems disappear the moment the person replies, which makes the reply the only thing the opener should be built to win.
Most 10DLC guides stop at the approval email. Carriers and their vetting partners do not. A registered campaign can be pulled back into review at random, suspended over a flagged link or a complaint spike, or frozen because someone edited it, and while it is down you cannot send, cannot move your numbers, and keep paying the monthly registration fee. Here is what actually triggers a post-approval suspension and how to see one coming.
RCS on iPhone made "just switch to RCS" sound like the free upgrade to green-bubble outreach. Then you read the onboarding. Business RCS needs a verified sender approved by Google and the carriers, a review measured in weeks, and an SMS fallback that still runs on your A2P 10DLC registration. Here is the part the channel's marketing leaves out.
No independent cross-industry benchmark for B2B demo show rates exists, and anyone quoting one precisely is quoting a vendor. Here is what can honestly be said, the math per point of show rate, and the levers that move it.
What daily volume each cold channel actually tolerates in 2026, what the carriers enforce in writing, and why the binding limit on results is list quality, not send count.
A factual walk through Sendblue's August 5, 2026 incident disclosure: what was accessed and when, the phishing campaign that surfaced it, what Sendblue handled well, and the security questions the episode should put on every messaging-vendor evaluation.
Cold email replied at 0.45% across 7.5 million sends in 2025 and roughly one in eight commercial emails never reached an inbox. A dated-numbers comparison of the two channels across deliverability, reply behavior, and thread persistence, plus the jobs where email still wins outright.
An iMessage drip is a timed series of individual blue-bubble messages that stops the moment the contact replies. Touch spacing, send windows, a copyable four-touch sequence, and the reply-handling mechanics that separate a conversation engine from an SMS blast with better bubbles.
A2P 10DLC registration governs one thing: sending on US SMS carrier rails. Channels that do not ride those rails require no registration, and iMessage is the one built for conversations. What registration actually demands, the path that requires none, and the compliance that applies either way.
Project Blue's published pricing: $300 per month plus a $500 setup fee on monthly billing, $166.50 per line per month on annual, additional lines from $250. The numbers, what they buy, and the setup-fee math nobody neutral has written down.

Most teams try to cut cost per demo by cutting cost per lead, which is the hardest lever on the board. The cheapest lever is the reply rate between paid lead and first conversation. Here is the full funnel math, where the leak lives, and a worked example with every assumption labeled.
