Ensure Your B2B Data Appending Includes Decay Protection!

Ensure Your B2B Data Appending Includes Decay Protection!

When you discover that the company you’ve dialed closed two years back, you know that your contact is outdated. When your team discovers that more than half of the contacts in your database are outdated, it’s recycled, and used for “cold calling” afterwards. Then with time, it’s transferred to newbies for “training purposes” and works as a simulator of sorts. And this is how your once-thriving client database dies. In marketing, we term this gradual regression as data decay. Data appending is the stimulant your marketing database needs to live a long and healthy life.

Maintaining a Healthy Data Profile with B2B Data Appending

While the data decay process seems long, the typical lifecycle of a B2B database is maximum 3 – 4 years. This translates to 25% erosion of your list every year. The average gap between successive changes of employers is two years, and change of email addresses is one year. These are the highest contributors to your B2B email list’s data decay. Continuous tracking of your professional-base can be achieved by enhanced hygiene & appending services.

Proper Hygiene Services ensure…

  • Increase in Deliverability
  • Reduction in Bounce Rates
  • Re-engaging with lost subscribers

On the other hand, appropriate Appending Services enable…

  • Increased Sales Opportunities
  • Sender Reputation Protection
  • Upselling and Cross-selling
  • Brand Recognition & Growth

The Importance of Decay Protection

How Data Appending & Hygiene Devices Differ

Appending services directly influence your database’s longevity and revives your old business relationships.  It fosters positive growth in your sales and revenue and is thereby beneficial on more than one ground. With higher number of competitors in all fields, courtesy to high digital exposure of individual businesses, the global B2B market will sooner or later saturate of choices.

In simple terms, there won’t be any more “new markets” to expand to. Client acquisition will take a step backwards, and client retention will take its place in the limelight. Some industry leaders are already showcasing their change in focus, by dedicating as much as 80% of yearly revenue accumulation target from their lists of existing customers.

Upheave Your Marketing Relevance with Data Appending

In marketing, reverse of decay is relevance. The more your email marketing efforts are able to establish real-time, quality and relevant communications with your clients, the decay factor of your list is minimized, if not eliminated.

But to apply this to an already decaying list means the initial business relationship conditions have to be re-evaluated.

Recognize the Living Persona of Your Decaying Email List

Step 1:

To start a new relation with your decaying client list, start with understanding their fundamental needs, like:


Your welcome mail can contain a brief, friendly questionnaire asking what they have been up to recently. Be careful on framing the questionnaire, so that it maintains the tone of decency and respect towards their privacy.


Step 2:

End the wait for your long listed subscribers. Give something back to them to start a genuine conversation.

The first mail is your acid test!


  • Keep Your Expectation Low

Apart from the fact that you have not contacted them for quite a while, 30% participants of any given list change their email addresses every year.

  • Don’t Be Pushy

This is not a cold call, or a sales pitch. So, do not sound like one! Sharing offers on your first mail is a strict no-no! Keep it to a normal greeting.

  • You need a Silver-Bullet Subject Line

Subject lines should be catchy, ensuring reader interest from the word go. 64% business mail recipients open the mails based only on the subject line.

  • Keep it Mobile-Friendly

You don’t know where they are, or what they are doing. Make your mail and landing page responsive. Over 80% of the people in the world check their mails in mobiles.


Step 3:

Time your 2nd mail accurately

You have (re-)engaged them. Good! Get the momentum rolling! Give them a valued resource (training material, documents) for free. Send the 2nd mail latest within a week of their response.


For non-responders, you can send the mail again after a two-week wait, but use a casual subject line, like “In case you missed this…” or something of that sort.

Follow the suggested response pattern below:
