How a campaign runs

CSV in.
Conversations out.

01

Share your list

CSV, Salesforce list view, HubSpot, BigQuery view, or a webhook stream. We map your variables per-call.

02

We match the agent

We design or reuse a voice agent for the campaign and personalise the opener with row variables — name, last order, balance.

03

We set the rules

Dial windows, retries, concurrency, DNC list, recording opt-in — agreed with you and set to the safe defaults.

04

We run & report

Live progress, real-time outcomes, paused or resumed on your say-so. Warm hand-offs go straight to your team's queue.

Compliance, built in

All the things
your legal team asks about.

Outbound is the most regulated channel a business has. Convexa handles Ofcom, PECR, UK GDPR, and TPS as built-in runtime guarantees — not docs — across every managed voice agent we run.

Ofcom dial windows

Caller-local 8 am – 9 pm enforced server-side. Bank-holiday calendars per UK nation. Calls outside the window are blocked, not retried at midnight.

TPS & CTPS scrubbing

Numbers checked against TPS, CTPS, plus your own internal suppression list, before every dial. 24-hour cache.

AI disclosure

Configurable up-front “this is an AI agent” line, with Ofcom Persistent Misuse Policy support. Auditable on every call.

Consent capture

Opt-ins and opt-outs captured as structured signals. Synced to your CRM and a central preference centre.

Retry logic that matters

Most "outbound dialers"
are bad at retry.

The right retry pattern can lift connection rates significantly — which matters whether you're running renewals or AI lead qualification. Our team tunes the pattern for your list as the campaign runs.

Default retry schedulesmart
Attempt 1 · busy / no-answer+ 1 h
Attempt 2 · same day+ 3 h, off-peak
Attempt 3 · next day+ 24 h, alternate window
Attempt 4 · final+ 3 days · then DNC
Voicemail policyleave on attempt 2
Per-number capconfigurable
Per-list learned schedulelearning

We fit a per-list connect-probability curve over the early dials, then target subsequent attempts at the times of day this cohort actually answers — which is rarely 9 am. Actual results vary by deployment, market, and call mix.
