Cadivra vs Coldreach (2026)
The decision is whether a person signs off, and these two are as far apart on it as this index gets. Cadivra makes approval unconditional and markets it as the guarantee: you review every email before it sends, nothing leaves your mailbox without your sign off, you preview a sample before committing to a campaign, and you can edit any individual message by hand. Everywhere else in this index approval is a setting an administrator may enable or an autonomy dial a customer may turn up. Coldreach defines the product category by its absence, describing an AI sales development representative as software that independently decides who to reach out to and what to say without a person writing each email, and it markets an auto pilot mode running around the clock. What the Coldreach operator controls is upstream: a plain English description of what counts as a buying signal, and instructions shaping tone. Both govern what the system looks for and how it sounds. Neither governs whether any individual message should go.
- Approval cannot be a setting somebody can switch off. Nothing sends without your sign off, a sample preview comes before you commit to a campaign, every message is editable by hand, follow ups halt the moment a recipient replies, and a suppression list is a first class object in the product rather than a feature.
- There should be no second domain to warm. Sending runs from your existing Microsoft or Google mailbox so you inherit your own established reputation, with sender authentication checked and explained in plain terms, four major blocklists monitored, sends paced under provider limits, a business hours window, and a sender health score with one tap remediation.
- You want the model provider named. Cadivra states outright which provider recombines its library of offers, problems, proof points and calls to action against each recipient's role, company and the operator's own notes, which is the first such naming recorded in this index.
- Your buying signal is not a filter box. The operator describes the trigger in plain English, from hiring three or more engineers with a named framework to a regulatory filing mentioning a particular initiative, and the vendor states there are no preset categories, so matching is comprehension rather than field comparison.
- You need the monitoring to run continuously and at scale. More than one hundred and thirteen million companies are watched against your description across five or more sources, with the account list refreshed and exported weekly, and researched leads, sent activity and replies pushed into your own system of record from the second tier upward.
- You want an outcome published with its denominator. Coldreach reports one thousand seven hundred and sixty eight leads reached, one hundred and three replies and thirty four interested leads in a customer's first month, and publishes its own attempts alongside its own meetings rather than only the meetings.

The short version of each
Cadivra
Cadivra is a British outbound tool built around an explicit rejection of the volume playbook, finding prospects by role, industry, location and company size, researching each company's site, filings and recent buying signals, writing a distinct email per prospect rather than a template with merge tags, and sending it from the operator's own existing mailbox. The GTM Tech Index grades it A on deliverability discipline, the most complete published posture for the email channel in the index and from its newest and smallest vendor: sending from the operator's existing mailbox means there is deliberately no secondary domain to warm, and on top of that sits a named control set covering authentication, blocklist monitoring, provider limit pacing, a business hours window and a sender health score with remediation.

Coldreach
Coldreach is a development agent built on the premise that the reason to contact an account matters more than the contact details, where the operator describes a buying signal in plain English and the system monitors more than one hundred and thirteen million companies against it across five or more sources before researching each match and writing an email that opens with the finding. The GTM Tech Index grades it B on operational and outcome evidence for publishing figures with denominators attached, including its own internal numbers stating ten to fifteen qualified meetings a week from seven to eight hundred outreach attempts. The index records the counterweight: a genuine reply rate across a real sample is framed against an unsourced baseline far below published benchmarks for the channel.

Common questions
Is Cadivra better than Coldreach?
Whether a person signs off decides it, and these two are as far apart on that as this index gets. Cadivra makes approval unconditional and markets it as the guarantee: nothing leaves your mailbox without your sign off, with a sample preview before you commit and per email editing afterwards. Coldreach defines the product category by the absence of a human in the loop and markets an auto pilot mode running around the clock. If your compliance review needs a named person to have chosen to send each message, Coldreach does not do that and does not claim to.
Which one tells you what AI it runs on?
Cadivra names its provider outright, stating which one recombines its library of offers, problems, proof points and calls to action against each recipient's role and company, which is the first such naming in this index. Coldreach names no provider, family or version anywhere, and instead publishes unusually specific mechanism disclosure: the document classes read for each lead, covering the company website, the regulatory filing, the hiring page, recent news and social activity, and what is extracted from them, being the pain point, the status quo and the urgency.
Which protects my sending reputation better?
Cadivra, and the GTM Tech Index grades it A on that axis, the most complete published email deliverability posture it holds. Sending runs from the operator's own existing mailbox so there is deliberately no secondary domain to warm, with authentication checked and explained, four major blocklists monitored, provider limit pacing, a business hours window, optional contact verification before a credit is spent, and a sender health score with remediation. Coldreach grades B, naming the three authentication standards individually and including warmup and pacing on every tier, while never describing whether messages leave from the buyer's mailbox or the vendor's infrastructure.
Where do Cadivra and Coldreach get contact data?
Neither names a supplier. Cadivra searches a business database by role, industry, location and company size and returns verified work emails, with no supplier, licensing arrangement, collection method, refresh cadence or accuracy claim published, and no route for a person in it to see or remove their record. Coldreach names source types rather than suppliers, listing job postings, company news, website content, social posts, employee changes and securities filings, and describes nothing about where the enriched email addresses come from. Both are graded C on that axis.
How much do Cadivra and Coldreach cost?
Cadivra publishes an entry price of twenty four pounds a month with a hundred free credits and no card required, and states the consumption economics plainly at one credit per contact with the preview email reused at no extra charge and a running ledger shown before a campaign generates. Coldreach publishes five figures from 899 to 3,000 dollars a month with no volume attached to any of them, no pricing page in the navigation, and its own blog stating a different entry figure from its homepage.
How does the GTM Tech Index grade Cadivra and Coldreach?
Both are graded on the same seventeen capability and compliance axes from public sources, at documented depths of sixteen and seventeen. Both take A on AI centrality. The GTM Tech Index grades Cadivra A on deliverability discipline against B for Coldreach, and B on autonomy and oversight, AI disclosure, outreach compliance and platform terms exposure. Coldreach takes B on AI disclosure, operational evidence, ecosystem depth and deliverability. Cadivra carries the pair's only D, on operational and outcome evidence, recorded as a stage fact for a company incorporated within the last year. The index publishes no composite score and declares no winner.

Both vendors publish something that does not survive checking, in opposite ways, and the difference between the two is worth drawing carefully. Coldreach's underlying figure is real and unusually well supported: a reply rate of three point eight percent across more than five hundred thousand messages is a genuine sample, and the vendor publishes its own internal numbers with the denominator included, ten to fifteen qualified meetings a week from seven to eight hundred outreach attempts, which almost nobody in this category does.
The framing around it is the problem. That rate is presented as roughly ten times an industry baseline of nought point three to nought point five percent, and the baseline is unsourced and sits far below widely published benchmarks for the same channel, several of which put the average above three percent. The multiple therefore depends almost entirely on which baseline was chosen, and the honest reading is that a good figure has been made to look extraordinary.
Cadivra publishes no customer evidence at all, and its demonstration section is headed as a real example, showing a composed email to a named contact at a named company followed by a reply timestamped eight minutes later. The companies appearing in it could not be located as real businesses.
This index records that as observed rather than concluding what it means, and records the stage alongside it: the company was incorporated within the last year and its domain registered in April 2026, so it has had months rather than years to accumulate a record, and a vendor cannot publish customers it does not yet have. Ask Coldreach which baseline it used, and ask Cadivra for a customer who will take a call.
