The cost benefit of an email subscriber

A while back I helped with some comms planning for a web project that aimed to link members of the community with groups and clubs in their area.

There were more than half a dozen around the table. On the face of it, I quietly reflected that this was worthy but what was the point?

My misgivings were answered by a bright community worker. He told the story of a hypothetical man aged 66 who had just lost his wife. He may start drinking. He may start getting ill and see his GP. He may start being a nuisance to neighbours and the housing authority and police may get involved. All of this costs the taxpayer spiralling amounts of money. Suddenly, the project came alive. We could attach a financial value to the benefit it brought.

“Oh no,” another voice around the table said. “We would never work that out. That’s not what we do.”

But it’s the voice of the bright spark we need to listen to and the naysayer we don’t.

I’ve blogged before that we need to look finance in the eye. We absolutely need to justify what we do and using pounds shillings and pence.

Now, a massively useful tool is with us. The download ‘Measuring the Financial Value of a Subscriber’ has been published by Govdelivery at the Public Sector Communications conference in London. They’ve worked with respected communications consultant and academic Guy Dominy to work out the value of an email subscriber. The figures and approach, they say, translate to social media too.

Dominy nails it in the opening paragraph:

“The demand for financial accountability is now more than ever before one that public sector communications can no longer afford to ignore. This means we must not only be able to say exactly what we are investing in our communications but we must also place a financial value on the impact of our communications.”

I couldn’t agree more.

Forget likes, sign-ups and shares. The real test of how effective your communications is what people have done as a result. This is what AMEC’s Barcelona Principles addresses. After research, the Govdelivery whitepaper shows the value of an email subscriber is £1.51. That calculates the benefit to the individual, the organisation and society in general.

Here are some numbers to think on

Weather warnings – Every death on the roads costs £2 million, serious injury £200,000 and minor injury £23,000. They’re Department for Transport figures. So reducing this figure saves drivers, fire, police and NHS staff.

FOI – costs local government £35.5 million in staff time with 121,000 requests costing £293 each. Better communications to keep people informed can reduce this.

Children in care – the cost of sending children into the private sector can cost more than £120,000. The cost of fostering in-house can be less than £30,000.

They’re three of the hundreds of things that government – local or central – does but dig and you have numbers attached. Dominy argues that there is value in that:

“Conceptually, you multiply the probability a subscriber will carry out a particular action by the financial value of that action. If a subscriber has a one in ten chance of doing something that is worth £1,000 to you, that subscriber is worth £100 to you.”

The good news is that Dominy sets out a process to help you calculate the value to individuals, organisations and society.
