What’s the secret to a successful email campaign?
Great design? Engaging subject lines and email copy? Your offer?
It's actually none of these things - while each, in itself, is important, the most crucial aspect of a successful email campaign is a quality email list.
A quality email list is one you've built through connection with your audience, based on their registered interest, and ideally, segmented by each person's preferences.
So how can you build a great, effective e-mail list? How can you get more warm leads onto your database in order to target them with your future offers?
Here are some tips.
1. Website/blog is the best place to take the first step
Your website or blog is generally the first thing people visit - so leverage the power of your website and place an email sign-up form on it.
When a visitor lands on your blog or site, give him/her a reason to subscribe - offer something valuable in exchange for their information. This could be an educational resource, eBook, white paper, special discount, free demo, or some other incentives.

2. Use the power of content upgrade
Brian Dean says that content upgrade increased his conversion rate from 0.54% to 4.82%. That’s 785%.
Nathan Ellering, Content Marketing Lead at CoSchedule, shared his take here:
“Content upgrade is an absolute best way to build an email list of active subscribers, just like how we've built a list of more than 100,000 subscribers at CoSchedule."
If you’re not using the power of content upgrade, you’re missing a great opportunity to build your email list.
Create an informational and interesting article, and offer an actionable cheatsheet or quick guide as an upgrade. Add a line at the beginning, middle or end of the post which encourages visitors to download your cheat sheet or guide.
Here’s a content upgrade example from Brian Dean:

3. Put a signup button on your Facebook Page
Social media is a great medium through which to build an audience, and you can also use it to grow your email list.
Add a 'Sign up' call to action button to your Facebook Page to collect email addresses - it’s a great way to convert your fans/followers into your subscribers.

4. Hosting a Webinar
Hosting a webinar can be a great way to communicate with your targeted audience - and collect email addresses.
The best way to do this is to find trending topic relevant to your service, then conduct a webinar based on that subject. You can then ask potential attendees to provide their contact information in order to join the webinar - and don’t forget to promote it across the social media platforms.

5. Run a Facebook contest
Facebook is also a great channel to run a contest or special offer (Instagram, too, can be beneficial on this front)
Create a compelling graphic, engaging title and an irresistible giveaway, then ask your audience for their email address in order to join the contest.
