Want to boost productivity and improve email deliverability?

Fortunately, you don’t have to navigate this alone—we’ve put together a helpful set of tips and tricks to help you get more potential customers and reach the full potential of your email marketing campaigns.

Let’s start with the basics.

What is an email list?

An email list is a collection of email addresses gathered by companies from clients who want to receive newsletters, exclusive content, discounts, and other promotional material.

With the help of a high-quality email list, you can reach out to people who are interested in your products or services, spark their interest, and keep them updated about upcoming releases.

Why should you build an email list?

The magic of mailing lists lies in the numbers. Here’s the scoop—email marketing has an astonishing average return on investment (ROI) for businesses in the US: 4400%. Impressive, isn’t it?

Check out the statistics:

And this is only the tip of the iceberg.

Connect to a larger audience

Email marketing is a cost-effective way to connect with your leads. While paid search and social media ads can also bring profit, they demand considerable financial resources and sometimes don’t pay off.

In contrast, email campaigns allow you to deliver your message to a broad audience at a much lower cost. And if you think that email outreach is an archaic tool, keep in mind that 34% of Americans and 99% of people around the globe check their inboxes throughout the day. It would be a pity to miss such a great opportunity, right?

#2. Implement opt-in consent

In email marketing, the opt-in approach allows you to target your sales toward people who are genuinely interested in your products and services. This is a form of inbound email marketing where you give your prospects a choice whether they want to receive your emails or not. If a potential client opts in, this means they would like to learn more about your company and potentially make a purchase.

Adding the opt-in button in your copy helps you build an email list of new subscribers who most likely will engage with your campaigns, reducing the risk of spam complaints and improving your deliverability rate.

#3. Create striking popup forms

Popup forms are effective tools for building strong email lists that will come in handy for sending marketing offers, promo campaigns, or new feature announcements. By adding an engaging popup on your website, you will be able to collect email addresses from people who are actually willing to share them.

For example, you can add a popup encouraging website visitors to subscribe to your newsletter to never miss out on important updates:

Popup example
Source: GetResponse

Pop-up forms are dynamic in nature, and they are a great way to deliver lead magnets for successful prospecting. You can set them to appear at certain times or for specific events to complement your marketing efforts.

#4. Offer real value

Let your prospective and current customers know about all the awesome goodies coming their way! We’re talking exclusive discount codes, access to advanced features of your product, or free gift offers that they won’t say ‘no’ to.

Providing a clear perk motivates your leads to willingly share their email addresses and even phone numbers, increasing the likelihood of a positive engagement.

#5. Optimize for mobile

Your sign up forms,  pop ups, and emails should always be mobile-friendly. Make things easy for your website visitors, whether they use a smartphone, tablet, or any other device.

Mobile-friendly content ensures that your potential customers will have a positive experience and, as a result, will be more inclined to engage with your emails, share their contacts, and maybe even accept your offer.

Snovio mobile example

#6. Deliver enticing content

Build brand awareness and keep the good vibes flowing by consistently delivering top-notch copy—anything from a relevant blog post to an educational presentation should regularly land in the inboxes of your subscribers.

Stick to a strict schedule so they always have something exciting to look forward to. Consistency builds trust, and interactive engagement keeps your prospects and customers interested. It’s a win-win situation.


#7. Leverage referrals

Referral programs are a good incentive for subscribers to spread the word about your offers to their friends, family, and colleagues, boosting your email list. When the perks are appealing, why not extend the goodness to more people you care about? It’s an email marketing strategy that absolutely pays off!

Attract new participants to your referral program with enticing perks like complimentary shipping, a $10 coupon, a 30% discount, or a delightful free gift. These irresistible incentives can do wonders, expanding your email lists and welcoming potential new customers to join.

#8. Use a chatbot

Chatbots are helpful tools that facilitate communication with your customers and offer 24/7 support service. In addition, you can use them to advertise your promo campaigns, sales, etc.

For example, you can offer exclusive content and deals to customers who sign up for your email list via your website.

#9. Join forces with other businesses

Teamwork in marketing isn’t just about spreading the word; it’s your secret sauce for boosting brand recognition and solidifying your business as a trusted authority.

Forge alliances with brands that complement yours in the industry. This opens the door to their audience, unlocking opportunities to connect with new leads who might fall in love with what you offer.


🌟Food for Thought. Let’s say you own a sports equipment business and want to collaborate with other companies to build your email list. Here’s an example:

1. Cross-promotion giveaway:

  • Partner with a healthy nutrition company or a fitness apparel brand.
  • Plan a joint giveaway where participants have to sign up for both of your newsletters to enter the contest.
  • Create a landing page for the giveaway, emphasizing the value participants will receive from both businesses.
  • Promote the giveaway through your respective email lists, social media, and websites.

2. Co-hosted webinars & workshops:

  • Select a health and wellness merchant who offers services or products that align with your fitness brand.
  • Host a webinar or virtual workshop together on a topic of mutual interest.
  • Participants register for the event, providing their email addresses, and both businesses gain exposure to each other’s audiences.

3. Guest blogging:

  • Identify businesses in the fitness or wellness industry that host a blog.
  • Identify businesses in the fitness or wellness industry that host a blog.
  • Propose an exchange where you write a high-quality article for their audience and vice versa.
  • Include a call-to-action in the guest post, encouraging readers to subscribe to your newsletter for more valuable content.

#10. Source email addresses offline

Consider using “old-timey” methods like attending networking events, contacting acquaintances for referrals, or cold-calling to gather contacts. These strategies may seem outdated, but they can still help you expand your email lists. So, it might be worth considering these traditional methods alongside newer digital strategies like social media and email marketing.

Here’s what you can do:

  • Network smart. Exchange business cards with people you meet. Add received contacts to your database.
  • In-person = email potential: If you’re rocking offline sales, ask your customers to share their emails with you.
  • Community vibes: Organize meetings for people from your industry or for those who might be interested in your product. Prepare a registration form with an email address column.

As you can see, there are a number of ways you can expand your database and get more prospects. But you should also keep in mind that not all strategies are that helpful. SOme of them can stall your progress or even harm your reputation.

Let’s take a look.

The don’ts of building an email list

#1 Purchased email lists

#2. Hidden opt-ins and pre-checked boxes

#3. Neglecting privacy and compliance with guidelines

#4. Over-emailing

#5. Ignoring analytics and feedback

#1. Purchased email lists

Say no to buying contact lists. The allure of affordable and readily available databases is understandable for busy business owners juggling multiple responsibilities. However, when it comes to email marketing, there’s no quick fix or magic solution. Here’s why:

  • Copycat alert. Purchasing email lists often means that somebody else has already got it too, and even more companies may get it in the future.
  • It’s a pitfall. These fake emails are strategically placed to lure in unsuspecting senders. Major service providers will mark you a spammer, and restoring your email reputation is no walk in the park. As a savvy business owner, steer clear of “sticky” situations.
  • Low duality contacts. These people have no idea who you are and what your business is. They didn’t agree to receive email campaigns from you, so chances are high that they will mark your messages as spam and harm your sender reputation. Not good.

#2. Hidden opt-ins and pre-checked boxes

Avoid concealing opt-in checkboxes or sneakily pre-checking them without getting a clear nod of agreement from your prospects. Make sure your audience willingly agrees to receive updates from you before you start targeting your campaigns toward them.

#3. Neglecting privacy and compliance with guidelines

Ignore data protection laws and privacy regulations, and you’re sailing into risky waters. Falling out of line with regulations can lead to serious legal repercussions and a tarnished brand image. It’s crucial to align your practices with: 

  • General Data Protection Regulation (GDPR): If you don’t have any record of your audience agreeing to receive your messages, you could be hit with some pretty hefty fees.
  • Controlling the Assault of Non-Solicited Pornography And Marketing Act (CAN-SPAM Act): This law sets rules for commercial messages and requires email senders to include opt-out options in their messages.


#4. Over-emailing

Sending too many emails can lead to subscriber fatigue and higher unsubscribe rates. Find the right balance to keep your audience engaged without overwhelming them. Remember, quality over quantity ensures that each interaction holds value and fosters a lasting and positive relationship with your audience.

#5. Ignoring analytics and feedback

Keeping an eye on your analytics is vital in getting your email game on point. And don’t forget, feedback from your subscribers is valuable, too! If you ignore these things, you could be holding your email list back from reaching its full potential.

Wrapping Up 

Now that you have all the necessary tools and information, you are ready to create the most effective email list you have ever had. With the right approach and consistent effort, you can build a loyal and engaged audience and achieve your marketing goals!


  • How are email lists generated?

    Email lists can be generated through various methods, depending on the purpose and context. For example, some common ways include opt-in forms on websites, social media platforms, referral programs, and more.
  • Why you should build an email list?

    This is a valuable asset that allows businesses to engage with their audience directly, deliver personalized content, and drive measurable results in terms of traffic, sales, and brand loyalty.
  • Can you legally buy email lists?

    While purchasing email lists is not illegal per se, sending messages without consent from the recipients is generally illegal and can result in severe penalties, including fines and legal action. It's essential for businesses to comply with applicable laws and regulations when collecting, storing, and using email lists for marketing purposes.
  • Is buying email lists worth it?

    Buying email lists is generally not worth it. You will probably get low-quality leads, receive spam complaints, and damage your brand reputation. We strongly recommend implementing organic list-building strategies.
