Sentry's Email Marketing service designs, builds and runs campaigns, always-on automated flows and behaviour-based segmentation across the list you already own, so the highest-margin channel you have stops sitting idle.

Campaigns, automated flows and behaviour-based segmentation that make owned email your highest-return channel — designed, built, scheduled and continuously improved.

## What it does

Designs, builds and runs campaigns, always-on automated flows and behaviour-based segmentation across the list you already own.

## Where it creates value

The compounding-retention stage: it converts one-off acquisition into repeat revenue and lifetime value at near-zero marginal cost — the highest-margin channel in the business.

## Why it cannot be ignored

An unworked list is revenue you have already paid for and left on the table. Every day without flows is carts not recovered, customers not reactivated and sender trust decaying — money you are choosing not to collect.

## What you get

- **Always-on flows** — Welcome, abandoned-cart, post-purchase and win-back automations working 24/7.
- **Segmentation** — Behaviour- and value-based audiences so the right message finds the right person.
- **Deliverability** — List hygiene and sender trust so messages reliably land in the inbox.

## Questions and answers

### Which automated email flows do you build?

Welcome, abandoned-cart, post-purchase and win-back flows, running continuously rather than as one-off sends. These are the automations that recover revenue you have already paid to acquire, which is why Sentry builds them before adding more campaign volume on top.

### Our emails end up in spam. Can that be fixed?

Usually, and it is treated as a foundation rather than an extra. Sentry works on list hygiene and sender trust, because deliverability decays quietly: every send to a stale list costs a little more reputation, until messages that people asked for stop arriving. There is no point improving the copy of an email nobody receives.

### We already have a list but we barely use it. Is that enough to start?

It is the strongest starting position there is. An unworked list is revenue you have already paid for and left on the table — carts not recovered, customers not reactivated, sender trust decaying. Sentry starts by segmenting what you already own by behaviour and value before spending anything on acquiring more names.

### How is this different from just sending more emails?

Volume without segmentation accelerates list decay. Sentry builds behaviour- and value-based audiences so the right message reaches the right person, and measures the channel on revenue contribution rather than opens. Sending more to everyone is the reliable way to make an email programme worse.

### What does managed email marketing cost?

Sentry's managed services start at £3,000 per month, scoped to the work, with third-party tool costs for the services we manage included up to a fair-use cap; paid advertising spend is excluded. Managed services are priced as a percentage of your annual sales, and the percentage rises with the service level you choose — Protect, Enhance or Create. We confirm the figures in your quote.

### Does email work on its own, or does it need the paid side too?

It works on its own and compounds when paired. Owned email is where acquired demand is converted and repeat value is created, which is why Sentry runs paid media and owned email as one engine feeding the same pipeline where a client takes both.
