The guide
Can AI actually write outreach in your voice?
First Person Outbound, explained by SimplyB2B
Most AI outreach tools give every user the same borrowed tone, then call it personalisation. The result sounds like a bot cosplaying a salesperson, and recipients feel it. Voice-matching that holds up under scrutiny starts somewhere different: it reads what you have already written, not what you tell it about yourself.
Key takeaways
- Your voice is seeded from your own sent messages and posts, not a style questionnaire or a shared model.
- Every edit you make trains your own voiceprint and no one else's.
- Autonomy expands only as your edits shrink, so the output earns trust before it acts alone.
- A warm-up ramp and a fixed daily ceiling protect your account while the voice is being established.
- The reply-rate gap between generic AI outreach and genuine first-person outreach is real and measurable.
Can AI write outreach that sounds like me, not a bot?
Yes, but only if the AI learns from what you have already written. Tools that ask you to fill in a style form are guessing. A system that reads your own sent LinkedIn messages and posts has actual signal to work from. The output then reflects your sentence rhythm, your word choices, your way of opening a conversation.
The practical difference shows up fast. Generic AI outreach borrows a tone that sounds professional but belongs to no one. Recipients have read that same email from five other people this week. First-person outreach seeded from your own history reads the way you actually talk, because it was built from the way you actually talk.
SimplyB2B seeds each user's voice from their own sent messages and posts on a per-account basis. There is no shared model. If two founders use the platform, their outputs stay entirely separate.
Seed
Your sent messages and posts are read to build a per-account voiceprint
Draft
AI writes outreach from that voiceprint, not a shared template
Approve
You review every draft before anything is sent or acted on
Edit
Your corrections feed back into your voiceprint only, not a shared model
Graduate
Autonomy expands only as your edits shrink, proving accuracy
How does AI actually learn my writing style?
SimplyB2B reads your existing LinkedIn sent messages and posts to build a voiceprint. It is not a questionnaire and not a shared style template. The system identifies your sentence length, your tone, the phrases you reach for, and the way you close a thought. That pattern becomes the seed for everything written in your name.
Each time you edit a draft before approving it, that edit feeds back into your own voiceprint. The model does not update a shared pool. Your corrections belong only to you, which means the voice gets more accurate to you specifically over time, not more average across all users.
This is why two people at the same company using the same platform will produce noticeably different outreach. The output reflects individual writing history, not a company tone-of-voice document.
How do I know the AI won't go rogue and sound nothing like me?
Autonomy is not granted up front. Every message starts in an approve-everything mode where you read and edit before anything sends. As your edits shrink, the system treats that as evidence the output is accurate to your voice and gradually expands what it handles alone. You are not trusting a first draft with your reputation.
This graduation model matters because voice accuracy and account safety are the same problem. An output that does not sound like you is also an output you would not have sent, and sending things you would not have sent is how accounts get flagged or how relationships start wrong.
The fixed daily activity ceiling cannot be raised regardless of plan tier. Combined with per-account behavioural timing variance, this means your account never acts in a pattern that looks automated, even as autonomy grows.
Does AI-written outreach actually get replies, or does it still feel fake?
One B2B advisory practice running its entire outreach on SimplyB2B, in its own voice, recorded about a 31% reply rate on cold outreach over a single month: 172 genuine replies from 552 people contacted, against a 3 to 10 percent cold-outreach norm. That gap is not a copywriting trick. It is what happens when recipients read a message that sounds like a real person they could genuinely want to talk to.
The trust signals recipients read before they reply are not just the words. Profile age, post history, and mutual connections are things a rented persona or a borrowed-face robot cannot manufacture. When the outreach runs on your actual account, in your actual voice, those trust artifacts are already there.
That is the structural difference between first-person outbound and an AI SDR running on a fake identity. One borrows credibility it cannot earn. The other uses the credibility you have already built.
How is this different from tools like Waalaxy, lemlist, or 11x?
Most outreach tools are built around sequences and send volume. Voice is either absent or drawn from a questionnaire that produces the same generic professional tone for every user. SimplyB2B is built around a per-account voiceprint seeded from real writing history, with autonomy that expands only as accuracy is proven by shrinking edits.
The approach difference is not a feature list. It is a question of where the voice comes from. Questionnaire-based and template-based tools ask you to describe how you write. A system seeded from your actual messages observes how you write. Those are not the same starting point.
Tools that run on a shared model also mean your edits help everyone else's output. On SimplyB2B, your edits train only your voiceprint. The learning stays yours.
What do I need to get started, and what does it cost?
The free Voiceprint read shows you what the system sees in your existing writing before you spend anything. If you want AI-written posts and outreach drafts that you approve and send yourself, that is the Voice plan at $59 a month. You only pay once you connect an account, and every paid plan carries a 30-day money-back guarantee.
The Presence plan, from $199 a month, connects to your LinkedIn account directly using permissioned access with no password stored, revocable at any time. It runs connection requests, direct messages, comments, and follow-ups inside the fixed daily ceiling. Setup is free regardless of plan.
Founder Brendan Levin runs his own outbound on the same engine, which is a reasonable indicator of how much trust the people who built it place in it.
Common questions
Will recipients know the message was written by AI?
When outreach is seeded from your own writing history and runs on your own account, recipients see your profile, your post history, and your mutual connections alongside the message. The trust signals they read before deciding to reply are real, because the account is real. A message that sounds like you, from an account that is demonstrably yours, does not read as AI-generated.
Does SimplyB2B work on email as well as LinkedIn?
LinkedIn is the only productized channel right now. The platform handles connection requests, direct messages, comments, posts, and follow-ups. Email is not part of the current offering.
What happens to my voiceprint if I cancel?
Your LinkedIn account connection is permissioned and carries no stored password. You can revoke access at any time. Your voiceprint data belongs to your account and is not pooled into a shared model, so cancelling does not contribute your writing history to anyone else's output.
Can someone with a thin LinkedIn post history still get a useful voiceprint?
The voiceprint is seeded from sent messages as well as posts, so a founder who sends a lot of direct messages but posts rarely still has usable signal. The approve-and-edit phase also builds the voiceprint forward: early drafts are reviewed carefully, and the edits you make accelerate accuracy faster than post history alone.
