Clodura.AI vs Instantly (2026)
The decision is what approval means in the contract you are signing. Clodura makes it unconditional and builds its whole agent positioning on refusing autonomy: approval sits at a named position in a published six stage workflow between creation and execution, it is not a setting a customer can switch off, and the vendor publishes a negative capability list stating that the agent will never send emails autonomously, override approval settings, bypass compliance rules, or learn or change behaviour without human oversight. Instantly's agreement runs the other way on the channel carrying almost all of its volume. On email the buyer may configure the agent to generate, schedule and send without reviewing any message, and by electing not to review is deemed to have reviewed and approved the resulting campaigns. On voice the same vendor holds the strongest controls in this index after Salesforce, with calling windows the platform enforces, a block list the buyer may not edit without documented renewed consent, and a one call at a time throttle. The gate is absolute at one vendor and channel dependent at the other.
- You want the cost of every action published. Three purchase models appear in full, twelve subscription credit bands and eleven pay as you go bands in two currencies, and a conversion rate for every action wrapped in a live estimator that turns a credit budget into what a team can actually run.
- Sending should leave from your own mailbox. Clodura connects to the customer's own mail account, so the buyer carries and keeps their own domain reputation, against a counterpart that provisions and owns the sending domains and mailboxes under its own name and may reclaim them on exit.
- The deliverability apparatus should be deep. Warmup with gradual volume scaling, spam scoring across more than thirty filters with remediation guidance before send, inbox placement testing across major providers, and a four layer verification engine applied to every unlocked contact and available for external lists.
- You need the voice channel governed by controls you cannot disable. Calling windows are enforced by the platform for the recipient's location and never outside eight in the morning to nine at night local time, a block list cannot be edited without documented renewed consent, one call runs at a time, and scripting to simulate bulk calling is expressly prohibited.
- Provenance should include the vendor's own status as a broker. Instantly enumerates source classes including a data cooperative, states affirmatively in a statutory table what categories were sold or shared in the preceding twelve months, names the supplier behind its website visitor product outright, and bars buyers from reselling or redistributing anything obtained.
- You want the mailbox count off the meter. Unlimited connected sending accounts ship on every plan with a reciprocal warmup network, and outreach volume and model credits are sold as separate subscriptions, so a buyer can take the platform with no model access at all.

The short version of each
Clodura.AI
Clodura.AI is a single go to market platform running from database to closed deal, founded in Pune in 2015, combining a stated six hundred million business contacts with waterfall email and phone discovery, sequences, a built in dialer and a deliverability suite, priced in one credit currency with unlimited users on every plan. The GTM Tech Index grades it A on autonomy and oversight, arriving there by refusing autonomy rather than by constraining it: approval sits unconditionally between creation and execution in a published six stage workflow, and the vendor publishes a negative capability list including that the agent will never learn or change behaviour without human oversight, the only drift commitment in this corpus.

Instantly
Instantly is a cold email outreach platform operating as Foo Monk, LLC, combining unlimited connected sending accounts and a reciprocal warmup network with a stated 450 million contact database, verification, website visitor identification and agents covering lead finding, email writing, reply handling and outbound voice. The GTM Tech Index grades it B on autonomy and oversight for two opposite postures in one product: on email the agreement carries a deemed approval clause under which a buyer who elects not to review is treated as having approved the campaigns, while on voice the controls are the strongest in the index after Salesforce and cannot be switched off by the customer.

Common questions
Is Clodura.AI better than Instantly?
What approval means in the contract you sign. Clodura makes it unconditional, placing it at a named position in a published six stage workflow between creation and execution, and publishes a list of what the agent will never do including sending autonomously and overriding approval settings. Instantly's agreement carries a deemed approval clause on email: a buyer may configure the agent to generate, schedule and send without reviewing any message, and by electing not to review is deemed to have reviewed and approved the resulting campaigns.
Which one governs the voice channel?
Instantly's are the strongest in this index after Salesforce and they are not optional. Calling windows are enforced by the platform for the recipient's location and never outside eight in the morning to nine at night local time, a block list exists from which the buyer may not remove a number without documented renewed consent, one call runs at a time, scripting to simulate bulk calling is prohibited, and the vendor reserves the right to suspend on anomalous call patterns. Clodura ships a dialer with recording and local presence numbers and publishes no calling hours, registry method or recording consent position.
How much do Clodura.AI and Instantly cost?
Both publish completely and the index grades both A. Clodura gives three purchase models, twenty three credit bands across two of them, a conversion rate for every action and a live estimator, with unlimited users on one shared credit pool. Instantly prices three product lines separately with monthly allowances against each, add on rates published rather than quoted, per action consumption rates, sold infrastructure priced to the domain and mailbox, a stated no overage policy and credit expiry disclosed against its own interest.
Who owns the sending domains and mailboxes?
Clodura keeps it with the buyer and Instantly holds it. Clodura sends through the customer's own connected mail account, so the buyer carries and keeps their own domain reputation. Instantly provisions, registers, owns and operates the domains and mailboxes under its own name and billing, which moves enforcement risk off the buyer's primary identity, and its agreement states that the buyer acquires no ownership and no right to transfer or port any of it and that the vendor may reclaim it on exit.
Which one addresses outreach compliance?
Instantly, decisively, and the GTM Tech Index grades it A against C. Its agent terms name a federal telephone statute with its implementing rule cited by section, the telemarketing sales rule, registry requirements, named state solicitation acts, recording consent laws, a state artificial intelligence disclosure provision and four further national regimes, with an anti spam policy incorporated. Clodura publishes a data protection position and a do not sell route and names no outbound regime at all, on a platform shipping a dialer with recording enabled.
How does the GTM Tech Index grade Clodura.AI and Instantly?
Both are graded on the same seventeen capability and compliance axes from public sources, at documented depths of seventeen and sixteen. Both take A on commercial transparency. The GTM Tech Index grades Clodura.AI A on autonomy and oversight, where Instantly holds B, and B on AI disclosure, data privacy, data licensing, ecosystem depth, deliverability and segment coverage. Instantly takes A on outreach compliance posture, data privacy posture and data licensing and provenance, with a D on exit and data portability. The index publishes no composite score and declares no winner.

Other published head to head assessments involving these vendors or their closest peers. The full set for this category is on the Sales Engagement & Outreach page.
Both vendors' customer evidence contradicts itself in the same two ways, and both are checkable without leaving the vendor's own properties. On scale: Clodura's site claims more than twenty thousand go to market teams while its own review platform profile claims more than seventy three thousand sales professionals, and the two are never reconciled.
Instantly's homepage claims more than fifty thousand sales teams while its own review platform profile says more than twenty thousand customers. In each case the vendor supplied both numbers. On testimonials the failure is sharper at Instantly.
An identical statistics block reading four times the reply rate, twice as fast to start and thirty percent higher inbox placement is attached to all three different testimonials, so the same three numbers are presented as three separate customer results with no measurement basis behind any of them, and one named testimonial is attributed to a co founder of one company on the homepage and to a head of growth at a different company on the pricing page.
Clodura's version is a choice rather than an error: every testimonial on its site is anonymised to an initial or carries no name at all, only a role, while substantial named enterprise logos sit on the same page, so the vendor has the references and does not attach them. Its quantified claims arrive in volume with no method behind any of them, and one, a claimed hundred percent connectivity rate on the phone product, is not credible on its face.
What both do have is real: named enterprise logos at one, three testimonials with names, titles and companies at the other, and a publicly identifiable corporate record at both. Ask each which figure is current and what period it covers.
