5 Ways to Grow Your Email Subscriber List

Email marketing is a great way to connect with customers on a regular basis and remind them of your services and marketing initiatives. Reaching your customers on a monthly or quarterly basis will (ideally) have them considering their HVAC and home performance during every season. Email campaigns are not only an excellent opportunity to educate customers, but are also a great way to remind customers to tune-up their AC unit or schedule that energy audit.

If you are sending to the same list of 100 people every month, you might not be seeing the desired return on investment. Consistently growing your email list increases your reach to people, boosting your company’s brand and message with each email campaign you send. There are a million ways to buy email lists online, but these are often unreliable, and could get you in trouble with the CAN-SPAM act (a law passed in 2003 controlling unsolicited commercial emails) if recipients have not “opted in” to your email list.

The Value of Your List Beyond Email

This post is focused on email, but in today’s marketing environment, the value of your house list extends well beyond that one medium. A strong list opens the door to connecting with customers on other platforms, like Facebook and other social media. You can upload a list of customers to Facebook, create a “custom audience” and target them with paid ads, and create “lookalike” audiences that target users similar to your current list. LinkedIn allows you to download a list of your connections to grow your list. Or, use the emails you have collected to send review request emails.

Using your email list in creative ways increases the value of every email you collect.

Want to spice up your customer email list and see it grow? Here are five initiatives that you can add to your business that will make it easy for relevant customers to join:

1. Make collecting emails part of your service call

Each time your customers schedule a tune-up and inspection, they should fill out  form that requests an email. This can be collected while the appointment is being made, or during the job itself. There is a good chance you already have some process in place that collects customer phone numbers, addresses and emails. The final step is to be sure that every email collected ends up on your mailing list.

2. Put a form on your website

If a user is on your website, they are most likely willing to learn more about your company and future offers. A noticeable call to action to sign up for your newsletter can help grow your list of emails everyday. The footer is a common place to find a newsletter sign up form and you can even experiment with a lightbox ad that pops up over your website, forcing the user to either sign up for the newsletter or click out of the ad. It is important to make these signups as simple as possible so it’s not time consuming for the user. These signup forms can feed directly into an email system like Mailchimp or Constant Contact, through an API integration so you don’t have to spend time managing the list.

3. Sponsor a community event

A community fair or home show are perfect places to garner interest and emails. While the main goal of these events is to gain more customers, it is unlikely that someone will sign up for a $20,000 energy retrofit on a Saturday in the park. It’s much more likely that they will give you their email and maybe be sold on the job later on. A simple clipboard or Ipad available for everyone who comes to visit your booth can greatly increase engagement and the value of each interaction that day.

4. Integrate signups with social media

Social media is another great way to keep in touch with your customer base. People who visit your Facebook or LinkedIn pages are likely to be looking for more information about the company or offers that you are featuring. They’re perfect candidates to join your newsletter list. Mailchimp and Constant Contact both have great Facebook apps that allow people to sign up for newsletters directly from Facebook. Similarly, LinkedIn also allows you to download a list of your contacts.

5. Make a great newsletter

So, you’ve implemented all the steps above and your newsletter list is growing. Congratulations! If what you’re sending that list is boring or visually unappealing, though, people might be unsubscribing as fast as they are subscribing. Spend time to create a newsletter that people want to read -- it’s worth the effort. Including interesting and relevant articles, new offers, testimonials, videos and other buzzworthy content will keep people engaged and coming back for more. Make sure your newsletter, and your website are mobile friendly -- according to Litmus.com, 55% of webmail is opened through a mobile device!
