The claims have converged. The products haven't.
Read five LinkedIn outreach homepages and you will find the same three promises: AI that personalises every message, qualification that finds the right prospects, and automation that runs without you. The wording barely changes from one site to the next, which tells you almost nothing about the software sitting underneath it.
Three questions separate them, and none of the three shows up on a feature grid.
1. Does the AI write the message, or fill in a blank?
A template with merge fields, an AI-written opening line dropped into a fixed template, and a message generated end to end for one specific person are three different things, and all three get called personalisation. Dripify offers up to twenty variables plus an AI icebreaker. Expandi generates a genuinely original opener, though it caps it at roughly 275 characters on a daily credit allowance. Waalaxy generates at campaign level, so every prospect in that campaign receives the same text with the names swapped.
Follow-ups are where the gap shows up most clearly. Almost every tool generates the first message and then hands the follow-ups to a fixed sequence.
2. Is anything filtered before the invitation goes out?
Your LinkedIn invitations are a capped resource. Spend one on a prospect who was never a fit and you pay for it twice, once for the invitation itself and again in an acceptance rate that decays with every ignored request.
Most tools qualify upstream, through search filters and enrichment, then send to everyone who passed. A handful read each profile and decide one by one. Linked Helper skips prospects whose required fields are missing. PhantomBuster can qualify a lead out of a campaign. Expandi, HeyReach, Dripify, Waalaxy and Skylead do not gate at the profile level at all.
3. Do you still have to build campaigns?
Nobody markets this one, and it quietly costs the most hours. Every mainstream LinkedIn tool is built around the campaign: define a segment, write a sequence, launch it, maintain it, watch it decay, start again. Then multiply that by the number of buyer types you serve.
The agents that removed the campaign are almost all email-first. On LinkedIn specifically, very few tools run a continuous flow instead of discrete campaigns.
How to read a comparison, including ours
Any vendor comparison, ours included, is written by someone with an interest in the outcome. Two habits protect you. Check the pricing page yourself, because comparison tables go stale within a quarter and stale pricing is the most common error in them. And when a table shows one column with every box ticked and the others nearly empty, treat it as marketing rather than analysis.
The comparisons below name what each tool does well. Where a competitor beats us on a dimension, we say so.
