Revexa vs SDR, agency and email tools: which fits you in 2026?
2026-07-01 · 4 min read · Adam Axelsson, founder of Revexa
The question "which tool should we choose?" is asked the wrong way. The right question is: "which problem are we solving, and which option fits it best?" Here is an honest comparison of the options for B2B companies that want to reactivate dormant CRM leads in 2026.
What should you actually compare?
Most comparisons focus on features. That misses the point. What matters is:
- Who does the research work, and does it scale?
- Who handles timing: does the option know when a lead is worth contacting?
- Whose voice and domain do the emails go out from?
- What happens when a lead replies?
- What does it cost, and how does it lock you in?
Option 1: Hire an SDR
The classic solution. A dedicated person who works your dormant list.
Strengths: Full control, human judgment in every email, can also work the phone and LinkedIn.
Weaknesses: Costs a full salary plus onboarding and tools. And the structural problem remains: good reactivation requires research per company, which means a human can only cover a limited part of the list. In practice the SDR also gets pulled into new inbound, and the old list ends up last again.
Option 2: Outbound agency
An agency takes over outreach on a retainer.
Strengths: Fast to get going, no internal recruiting, proven processes.
Weaknesses: The agency's economics rest on volume across many clients, so deep research per lead is rarely profitable for them. The emails often go out from the agency's infrastructure rather than your domain, and the tone becomes the agency's, not your salesperson's. Dormant leads know you. An email that does not sound like you risks doing more harm than good. Lock in periods of 3 to 6 months are standard.
Option 3: Email tools and sequencers
Tools where you build sequences and send at volume yourself.
Strengths: Cheap per email, full control over copy, technically fast to get going.
Weaknesses: The tool does not write the emails, it sends them. Research, segmentation, timing and reply handling are still your job. In practice the result is often a generic sequence to the whole list, because that is the only thing that scales by hand. Against a dormant list, which already has a relationship with you, that is the worst possible use: the same email to everyone burns the trust capital.
Option 4: Do nothing
The most common option, though rarely a deliberate choice.
The cost: Industry studies show that 70 to 80 percent of CRM leads sit dormant. With a lead cost of a few thousand each, that is often a large sum of already paid lead generation sitting untouched, while contact data ages and gets worse every month.
Option 5: Revexa (Leo)
Leo is built for exactly this problem: dormant CRM leads. Leo watches the whole list and acts on signals: when a lead changes role, the company hires or a funding round is announced. Then Leo does real research on the company, writes a personal email that opens on the specific event and sends it from your own domain, in your salesperson's voice. Replies are handled and meetings are booked straight into the calendar, with a Lead Brief for the salesperson before each meeting.
Strengths: Research and signal tracking at scale, emails that sound like you, the whole chain from signal to booked meeting.
Weakness: A narrow niche. Leo is built to wake leads you already have, not for cold prospecting against new lists or for marketing in a broader sense.
Comparison table
| Factor | SDR | Agency | Email tool | Leo |
|---|---|---|---|---|
| Research per lead | Yes, but covers a subset | Rarely profitable for the agency | No, your job | Yes, per company |
| Signal driven timing | Manual, when time allows | No | No | Yes |
| Your domain and salesperson's voice | Yes | Often not | Yes, if you write yourself | Yes |
| Handles replies and books meetings | Yes | Partly | No | Yes |
| Pricing model | Fixed salary | Fixed retainer | Low, but the work remains | Performance based, you pay per booked meeting |
| Scales across the whole list | No | Partly, via volume | Yes, but generic | Yes |
The takeaway: the right tool for the right job
Do you need a human who also works the phone, events and complex accounts? Hire an SDR. Do you want to outsource broad outbound and accept the agency's voice? Bring in an agency. Do you have a team that can write, research and handle replies themselves? An email tool is enough.
But if the problem is the dormant CRM list (leads you have already paid for, that no one has time to research and that cannot take generic sends), then that is exactly the job Leo is built for.
