What is email marketing?

Email marketing involves sending targeted messages via email to promote products, services, or content. It's an effective way for businesses to connect with customers, nurture leads, drive sales, and foster brand loyalty. Using personalized content, newsletters, promotions, and updates, you can actively engage and convert recipients into customers or advocates for your brand.

Why is email marketing important for your brand?

In the era of post-iOS 14 and data privacy, email marketing is one of the few effective ways to retain customer data. It's certainly the only channel where you can keep first-party data and interact with your customer base on a more personal level.

With email, you can take leads from all your other marketing channels (like paid media, inbound marketing, or ads on social media platforms) and move them from the awareness stage to the consideration stage, all the way to making a purchase.

Email marketing is especially compelling for eCommerce brands, where a lot of the revenue comes from email marketing campaigns such as promotional emails, email newsletters, abandoned cart emails, etc.

What does an email marketing agency do?

An email marketing consultant or agency provides a range of email marketing services. They could do any number of things for your business depending on the kind of emails you already have set up and the size of your internal team.

Email marketing strategy

If your business doesn't have a comprehensive email strategy, then any good marketing agency's priority would be to start there. The first step would be to establish an email marketing plan and establish which email segments you have and which email campaigns you should have (promotional or transactional emails).

Tasks could include:

• Creating email segments
• Using email personalization
• SMS marketing strategy
• Conducting an email audit
• Launching a customer loyalty program

Email campaign management

Any digital agency specializing in email marketing usually creates your campaigns from scratch. That could include graphic designs, content creation, and even designing custom templates from scratch. A full-service email marketing agency usually has a copywriter, graphic designer, email strategist, and project manager on staff. If you're an eCommerce business, you want to use a specialized Klaviyo agency to manage your campaigns.

Tasks could include:

• Optimizing your cart abandonment campaigns
• Upgrading email newsletter design
• Improving email marketing funnels

Email automation

Another super important element of their work would be marketing automation—setting up the various email flows, personalized emails, and promotional campaigns to target specific segments of your email list. The science of email marketing is knowing how to send the right email messages at the right time to your potential customers, and that's where you need a professional email marketing firm to understand how to target your email audience optimally.

A/B testing

Then there's A/B testing, which is super important. It's the key to a successful email campaign. You want to maximize your customer engagement by testing different subject lines, promotions, CTA text, and content in the body of the email. Professional email agencies run tests to optimize the click, conversion, and open rates of emails.

Email deliverability

Last but not least, another service that a professional email marketing company could provide is email deliverability. Some business owners make mistakes and either break rules (like the CAN-SPAM Act) or buy mailing lists (a big no-no), and their reputation goes down with their email service provider (ESP).

So their emails stop getting into their customers' inboxes and instead either bounce or land in the spam folder. A professional email marketer would be able to warm up your domain, help improve your reputation with ESPs, and improve your deliverability rates.

Questions to ask your email marketing agency before you hire them

1. Which email marketing platforms do you have experience in?
2. What type of email content would you recommend we focus on?
3. Do you have experience launching successful SMS marketing campaigns?
4. How would you tweak our campaign strategy to help us increase our email revenue?
5. Do you charge a flat monthly fee or an hourly rate?
6. How would you increase our customer lifetime value?
7. Do you have extensive experience running omnichannel campaigns?
