A broken email database will lead you nowhere in your email campaign. By broken email database means incomplete email data. That's where email and phone append come into the picture.

Without proper information, connecting with your prospects feels like talking to a wall. You can't even guess whether your message gets seen or ignored if you don't have enough information. As a result, your marketing outcomes can fall flat.

That's why customer contact details like phone numbers and emails need to be appended. Let's talk about it in detail in this blog.

What does email and phone append mean

The process of email and phone appending involves adding missing email information to your customer database. It'll make sure that your contact details are filled with updated data. However, appending customer data, especially emails and phone numbers, requires hard skills and strong support.

Marketers consider "customer data" as a moving target because it changes over time. From emails, phone numbers, to addresses, each of these categories of data is changeable. Customers can change their emails, phone numbers, and residences over time. To connect with them, you need to keep your customer database updated and appended. Adding fresh information to your database is the right way to keep your database updated.

  • Email appending is simply a process of adding missing information to your existing email database. You can use data from third-party data sources to get your missing email information. From names to validating email servers, email appending includes everything. 
  • Phone appending follows the same concept. Here is the name of the customers, number codes, etc, that are getting added to the phone number database.

With the application of both appending concepts, i.e., email and phone numbers, you can run effective prescreen campaigns. It can help you run marketing operations better and effectively with the application of accurate data.

Reasons why email and phone append are a must for prescreen campaigns

Prescreen campaigns will become effective when you add relevant information to them. Having accurate data for emails and phone numbers is non-negotiable. You can outreach better when you have all the information aligned. So, here are the five best reasons you need to append your emails and phone numbers;

Reach the right audience

Delivering your message at the right time is crucial to getting the desired outcomes. In email and text message campaigning, getting things in the right direction is extremely important. Companies pay for each lead, and the cost is quite high here. Hence, having the email or phone number list accurate must be there.

Your brand messages (offers, deals, newly launched, personalized offers, etc) should reach your intended audience. If it's not getting landed in the right direction, it will become a huge burden for your company/efforts.

Ultimately, you need to keep your email list updated with accurate information.

Better response rate

In B2B operations, the email response rate is good, factually. People running the B2B operations prefer to get emails instead of trying out other new things. 

Sending emails to the right people should be your target here. Sending emails to the wrong person due to a lack of valid email data is not a choice here. Your email marketing campaigns can get hugely impacted because of that.

Instead, you need to append your email database with the right type of information for a better response rate. Because email appending ensures that you're getting all the active emails. When you send emails to active ID, it's natural that you'll get a better response. 

📌 Note: A good content strategy also plays a critical role in gaining a better response rate in emails. That means you have to equally focus on content strategy besides appending your emails. The same strategy applies to text message campaigns and cold call campaigns.

Increase customer satisfaction rate

The more information your marketing department gets, the more efficiency they can bring to your marketing campaigns. Email and phone number appending is a good marketing strategy that enables multichannel communication. It simply means you can reach your customers via multiple ways to deliver your message.

Ultimately, this helps your brand to provide customer satisfaction. Customers are getting your message from their preferred method of communication.

Phone and email appending make the entire marketing campaign convenient for your customers. As a brand, you can also understand which communication channels (emails or calls) are gaining more responses. With time, email data appending and phone appending help you strategize your marketing campaigns and increase the customer satisfaction rate further.

Accelerate the data accuracy rate

Customer outreach campaigns include numerous aspects that you have to handle efficiently to bring success to each campaign. For example, in email campaigns, you have to check that all emails in your database are error-free. Plus, you have to manage subscriber lists, unsubscriber lists, alternative email lists, and many other things.

Making a single mistake while entering email data can cause significant errors in your email campaign. It can impact your brand image, campaign budget, and other invisible costs. Similarly, you need to take special care of maintaining the phone number database.

Appending your email and phone number database increases data accuracy rates. Also, it can help sort and clean your database in the right way.

Email appending can help you with –

⦿ Cleansing your email database
⦿ Match emails
⦿ Send and manage emails
⦿ Monitor responses

For reference, following best practices for email appending ensures that all your email data is accurate and complete.

Minimize overhead costs

Appending is a process that makes sure your email and contact details are accurate. In turn, you can save overhead costs to a great extent over time.

Nowadays, marketers consider outsourcing the email appending part to save costs. Appending is a smart strategy. Marketers must embrace it.
