The Agency Email Marketing Cost Problem

A typical digital marketing agency managing email marketing for 10–25 clients faces a cost structure that erodes margins as clients grow. Klaviyo charges per contact — a client with 10,000 contacts costs approximately £130/month on that tool alone. Ten such clients cost £1,300/month in email platform fees before any agency margin is applied.

OptinMonster charges per site. Zapier charges per task. The costs compound.

Visisto's Agency plan changes this entirely: £199/month flat, unlimited contacts across all 25 client sites, all features included. An agency that previously paid £1,500–£2,500/month in combined tool fees pays £199/month and keeps the difference.

One Dashboard, 25 Isolated Client Workspaces

The Agency plan gives the agency a single login that accesses all client sites. Each client has their own isolated workspace with separate contacts, widgets, automations, broadcasts, and analytics. One client's data cannot be seen from another client's workspace.

Role-based access control allows the agency to:

  • Give account managers access to their specific client accounts only
  • Give clients viewer access to their own stats and reports without touching any settings
  • Restrict admin-level actions to senior team members

Onboarding a new client takes under an hour: create the workspace, install the Visisto script tag on their website, configure the first widget, and set up the initial automation. No new subscription, no billing change, no new account to manage.

A Widget Template Library That Deploys in Minutes

Agencies that manage multiple clients in the same vertical — ecommerce, hospitality, professional services — quickly identify the highest-performing widget and automation combinations. Visisto allows the agency to build their own template library: a proven spin wheel design, a high-converting exit-intent popup, an ecommerce abandoned-cart sequence.

When a new client onboards, the agency deploys their best-performing template to that client's site, customises the branding and copy for the client, and publishes. The first widget can be live within the onboarding call.

This is fundamentally different from the agency client experience with Mailchimp or Klaviyo, where every new client is a blank slate with no institutional knowledge carried over.

Visi AI Cuts Campaign Creation Time by 80%

The most time-intensive part of managing email marketing for multiple clients is content creation. Writing a welcome automation for a new client, drafting a broadcast for a seasonal promotion, generating a re-engagement sequence for a lapsed-member list — each of these takes hours when done from scratch.

Visi AI — the AI growth layer inside every Visisto account — generates complete multi-step automations and broadcast drafts from a single paragraph. The account manager describes the client's business, the campaign goal, and the target audience in plain English. Visi produces a full email sequence with subject lines, body copy, and send timing. The manager reviews, adjusts the tone to match the client's brand voice, and publishes.

What previously took 3 hours per client takes 20 minutes. For an agency managing 25 clients, this is a transformative efficiency gain.

Analytics That Make Client Reporting Simple

Every Visisto workspace includes full analytics: widget impression to conversion rates, email open and click rates, automation performance by step, broadcast engagement. The agency can pull a monthly report for each client from the dashboard without logging into five separate tools.

Visi AI surfaces the most important insight from each client's data automatically — identifying which widget is underperforming, which automation step has the highest drop-off, which email subject line style consistently outperforms — so the agency can present specific, data-driven recommendations in every client meeting.

The Financial Case

An agency with 10 clients, each with 5,000–15,000 contacts, typically pays:

  • Klaviyo: £800–£1,200/month across accounts
  • OptinMonster: £350–£500/month (Pro plan × sites)
  • Zapier: £150–£300/month in task fees
  • Total: £1,300–£2,000/month

Replacing all of this with Visisto Agency: £199/month flat. Saving: £1,100–£1,800/month. Annual saving: £13,200–£21,600.

The agency can pass some of this saving to clients as a competitive differentiator ("we use enterprise-grade tools without the per-contact overhead") or retain the full margin. Either way, profitability per client improves immediately.

What Visisto Replaces for Agencies

  • OptinMonster (per site) — replaced by Visisto's 20 widget types across all 25 client sites.
