Fluents + Hunter.io: AI Dialler for Every Contact Hunter Finds
Hunter.io finds verified email addresses for prospects at scale — from domain search, LinkedIn profiles, and company lookups. Most teams use Hunter to build email sequences. Fluents adds the voice channel on top: every contact Hunter surfaces can also receive an outbound AI call as part of a coordinated multi-channel sequence — email and voice running in parallel, or voice as a follow-up step for non-responders.
For sales teams and agencies that already use Hunter.io for cold outreach, adding Fluents is the difference between a single-channel email campaign and a multi-channel outbound stack where a prospect hears from you both in writing and by phone — which consistently outperforms either channel alone.
Multi-channel from the same list: Hunter.io sourced contacts feed directly into Fluents for voice outreach — email and AI calling running in parallel from the same prospect list
Non-responder voice follow-up: contacts who don't reply to Hunter.io email sequences trigger an AI voice call — adding the phone channel to prospects who've seen the email but haven't responded
Verified contact quality: Hunter.io's email verification means every contact passed to Fluents is a real, verified prospect — maximising call list quality and minimising wasted dial attempts

Email Alone Is a Single-Channel Bet
Hunter.io finds verified contacts. Email sequences get some of them to reply. But the majority of outbound email — even well-written, well-targeted email — goes unanswered. Adding a voice call to the same contacts, timed to land after the email has been seen, creates a multi-touch outbound motion where the prospect has been contacted across two channels before the follow-up sequence ends. Multi-channel sequences consistently outperform email-only sequences on both reply rate and meeting booking rate.
SDR Teams: Building the Multi-Channel Sequence
A sales development team using Hunter.io to source prospect emails and build sequences can use Fluents to add a voice step to the same contact list. The sequence runs: Hunter sources the email, email step 1 sends, email step 2 sends, Fluents voice call fires on day 5 for non-responders, email step 3 sends the day after for those who didn't answer the call. The prospect who ignores two emails but answers a phone call gets a qualification conversation they wouldn't have had in a pure email sequence.
Agencies: Scaling Multi-Channel for Multiple Clients
A lead generation agency using Hunter.io to build prospect lists for clients can use Fluents to add the voice dialler layer to every campaign. Hunter builds the list. Email outreach runs. Fluents calls non-responders or positive repliers depending on the campaign configuration. The agency delivers a multi-channel outbound service rather than email-only, improving client results and differentiation.
Domain-Based List Building + Instant Dialling
For targeted account-based outreach — where a sales team wants to reach every relevant contact at a list of target companies — Hunter.io's domain search combined with Fluents' power dialler creates a complete ABM voice outreach workflow. Hunter surfaces every relevant contact at the target domain. Fluents dials the list. Dispositions write to the CRM. The sales team has a worked account rather than a research spreadsheet.

FAQs
Questions about Fluents and Hunter.io.
Fluents connects to Hunter.io via API or through your CRM or outreach tool as middleware. Hunter-sourced contacts are passed to Fluents as a calling list, or specific events — such as a non-response after step 2 in your email sequence — trigger a Fluents call. Contact the team to configure your Hunter.io outbound workflow.
The Fluents agent references the email outreach context on the call — mentioning the email that was sent, the value proposition, and why the team is reaching out. The call opens as a warm follow-up to written outreach, not a cold dial. The script is configured to match the campaign's positioning and ICP. Contact the team to set up your Hunter.io follow-up call script.
Fluents dials the contact numbers provided in the prospect list. For campaigns where direct dial numbers are available alongside Hunter.io email addresses — from ZoomInfo, Apollo, or similar enrichment tools — Fluents will call those numbers. For email-only lists, Fluents can call a company's main number and ask to be connected. Contact the team to discuss phone number sourcing for your Hunter.io campaigns.
