If you’re choosing an email marketing platform based on price or aesthetics alone, you’re already leaking revenue.

Each platform is built for a different kind of business, and if you pick the wrong one, it won’t just slow you down. It’ll mess with your data, kill your deliverability, and make scaling a nightmare.

Here’s the no-BS breakdown of the tools we’ve tested, built with, and battle-proofed:

1. Flodesk

Use it if: You’re a service-based solopreneur, creative, or coach prioritizing design and simplicity over granular data.

Flodesk is beautiful, simple, and intuitive. But that comes at a cost, limited segmentation, weaker automation, and minimal analytics. Great for portfolios, small launches, and brand-based nurture. Not great for scaling with complexity.

Pros:

• Gorgeous templates

• Easy for beginners

• One flat price (even for big lists)

Cons:

• Weak automation logic

• No dynamic content or deep data

• No integrations with most advanced tools

2. Klaviyo

Use it if: You’re in e-commerce and you want to drive serious revenue through segmentation, dynamic content, and abandoned cart flows.

Klaviyo integrates beautifully with Shopify and product feeds. It’s data-rich and built to scale, but it comes with a learning curve.

Pros:

• Deep integration with Shopify

• Excellent for product automations

• Predictive analytics and smart targeting

Cons:

• Clunky for service businesses

• Higher cost as your list grows

• Not the most beginner-friendly UI

3. Go High Level (GHL)

Use it if: You’re a service provider or agency who wants one platform to run everything, from CRM and SMS to email and funnels.

Go High Level isn’t just email. It’s your whole backend. Ideal if you want an all-in-one sales and marketing machine. But if you’re only looking for email… overkill.

Pros:

• Full automation stack

• Built-in CRM, landing pages, booking tools

• White-label options for agencies

Cons:

• Steep learning curve

• UI can feel clunky

• Needs time and training to implement well

4. Mailchimp

Use it if: You’ve got a simple list, basic campaigns, and don’t want to deal with too much tech.

Mailchimp still does the job, just not the best job. Good for newsletters, one-off blasts, and businesses not yet ready for complex automation.

Pros:

• Familiar and easy to use

• Decent automation builder

• Lots of integrations

Cons:

• Segmenting can get messy

• Deliverability isn’t always great

• Pricing stacks fast with growth

Final Word: Pick the Platform That Matches Your Goals

Your email tool should match how you sell. Not just how it looks.
If you’re building long-term nurture, sharp segmentation, and automations that actually convert, it pays to choose the right engine from the start.

And if you’re not sure which one’s right for you?

That’s the kind of clarity we build into every strategy at Rewrite.
