Custom Email Template Design vs. Drag and Drop Builders: Pros and Cons

To be or not to be…

If Shakespeare were stuck in an email marketing meeting today, his big question wouldn’t be about life or death. It’d be this: Do we stick with drag-and-drop builders or invest in custom email template design?

And honestly, I’d feel sorry for him if he thought he had to pick just one.

Because the truth is that email design isn’t a loyalty test. Nor do an either-or approach is useful to it.

An effective email template design counts on using the right tool for the right job.

Sometimes, drag and drop email editors outsmart custom email designs. Other times, they fall short, and you have to go custom.

So instead of arguing over which is “better,” let’s do something more useful:

Let’s weigh the pros and cons of both approaches, so marketers and teams can make smarter workflow decisions as we dive into each option.

Because once you understand what each one brings to the table (and what it doesn’t), the smarter choice pretty much makes itself.

Custom Email Template Design: Pros

Whether you hire a custom email template design service or have an in-house developer, custom email templates are great at maintaining a high standard of branding across all email campaigns.

If drag-and-drop templates are off-the-rack, custom email template design is a tailored suit. It’s made to fit your brand guidelines, goals, and audience with precision.

As Drupal Singh, seasoned Project Manager at Mavlers, puts it:

“Custom email templates are like wearing a perfectly tailored suit—designed to fit your brand’s needs precisely.”

Here’s why more brands are choosing to use custom email designs for their campaigns:

• Full Design Control

No layout restrictions. Break symmetry. Add branded fonts. Design for dark mode. The design decision is in your hands thanks to custom HTML and CSS. Not your ESP’s drag-and-drop builder.

• Reusable Code Snippets

Custom doesn’t mean single-use. Build once and reuse indefinitely. Create modular snippets for headers, footers, product blocks, and more, making future campaigns quicker to assemble and scale.

• Custom Data Integration

With custom code, integrating data-driven content and personalization becomes seamless and more accurate.

• Advanced Interactivity

Interactive elements, such as accordions, sliders, countdown timers, and hover effects, become possible. The features most builders don’t support. And yes, you can still build fallback versions for less compatible email clients.

• Unique Layouts & Styling

It’s okay to want to design emails with uncommon design elements such as gradients, shadows, rounded buttons, border strokes, or a non-standard structure. Advanced CSS supports you to the fullest so that your emails feel unique and on-brand.

• Flexibility

You can adjust spacing, swap sections, or customize layout behaviors without being locked into a builder’s fixed structure.

• Better Rendering Across Clients

When done by experts, custom email templates render beautifully across all major clients. And with some smart QA, you can optimize for even the tricky ones.

• Cleaner Code = Better Deliverability

Custom-built templates are leaner. They don’t come packed with messy inline styles or bloated markup that builders often generate. This improves your inbox placement and sender reputation.

• Brand Consistency

Custom templates have your brand guidelines baked in and shine across devices, inboxes, and campaigns. That visual consistency solidifies trust.

Custom Email Template Design: Cons

Yes, custom-coded emails look sleek and professional. But getting there isn’t always smooth sailing. Here’s what you’re signing up for:

• Not Exactly Plug-and-Play

These aren’t your friendly drag-and-drop modules. Editing a custom HTML template without knowing your way around code is a dangerous territory. Unless you have a solid developer on call or are one yourself, editing even small details can be risky.

• Time Is a Real Cost

Speed is not a strong suit here. Unlike builders where you can whip something up in an hour, custom email design demands a build–test–fix–repeat cycle. And testing across Gmail, Apple Mail, Outlook, and a few dozen other clients? If you're racing toward a tight campaign deadline, that level of QA can feel like a bottleneck.

• Specialized Skills = Specialized Budget

Custom email design isn't a DIY YouTube tutorial kind of job. You’ll likely need a developer who understands the arcane rules of email code. (Hint: they’re not the same as web rules.) That niche expertise doesn’t come cheap.

• Complexity in Maintenance

Building a complex custom template is one thing. Keeping it up to date is another. Design tweaks, content changes, or client-specific updates can quickly escalate into mini-development cycles.

• Compatibility Challenges

Consistently displaying your custom email template across all email clients is the most challenging aspect of custom designs.

Drag-and-Drop Email Builders: Pros

If you’ve ever used a WYSIWYG editor (What You See Is What You Get), then you already get it. It's ridiculously easy.

For you to build a professional-looking email using these builders, you won’t need to be a coding or design pro. Your content managers, marketers, or non-technical professionals can also get started with email creation.

You will find these low-code/no-code email design features baked into the most popular ESPs and CRMs. Mailchimp, HubSpot, Salesforce, Iterable, to name a few. Some even let you edit the underlying code.

Here’s why drag-and-drop builders remain the go-to for fast, functional email creation:

• Code-Free Email Creation. You drag, you drop, you’re done with your email design. Without needing a developer.
• Real-Time Visual Editing. As you build, you see what your subscribers will see.
• Mobile-Ready by Default. Emails designed in these editors are automatically responsive.
• Design Consistency. Prebuilt blocks and brand-safe templates let you ensure an on-style email campaign without extra effort.
• Speed + Flexibility. You can craft your masterpiece from scratch or just grab a pre-made template and customize it. Either way, you're looking at gorgeous emails in no time flat.
• Cost-effective. No need to outsource email builds or burn dev hours. Pure genius if you're a lean, mean small business or a marketing team that moves faster than a squirrel on meth.

Drag-and-Drop Builders: Cons

Drag-and-drop editors make email creation feel simple. But scalable? Not always.

According to Drupal, using one is “kind of like building a prefabricated home.” Yes, it’s fast and gets the job done, but if you have a detailed, distinctive, on-brand vision, drag-and-drop would seldom suffice.

Here’s where drag-and-drop builders often fall short:

• Design Freedom Only to a Point. You’re limited to what the builder offers. Basic blocks, standard layouts, and some style customizations. But an advanced design or a layout that breaks the mold would be hard to find.
• Lack of Precision. Now, this can be a downside for some, but not all, editors. You may notice things feel “off.” Spacing issues, weird text wrapping, or a button that floats funny on mobile. And unless you know how to edit code, you’re stuck watching it go live that way.
• Your Email Looks Like Everyone Else’s. These tools are used by thousands of businesses. Chances are, your subscriber has seen the email template you chose before, from someone else.
• Compatibility gremlins. Older email clients don't render drag-and-drop emails perfectly.

Custom Design or Drag-and-Drop? What Works Best—and When

Still on the fence between coding HTML emails from scratch or using a drag-and-drop builder? Let us help you break it down:

Choose a Drag-and-Drop Builder if:

You need to create email designs and get them out the door fast. These tools are also ideal for teams without in-house developers or designers. They let you whip up standard, polished email campaigns without playing with code. If an email doesn't need pixel-perfect customization, such as a newsletter or a quick promotional message, it’s a solid fit for a drag-and-drop builder.

Go Custom When:

You care deeply about design control, brand alignment, and how your email looks across every device and inbox. Custom coded email templates are the right call when your brand guidelines are strict. Or when you’re building something advanced—like interactive elements, dynamic personalization, or modular systems your team can reuse.

DIY editors work well until they don’t. The minute your marketing needs outgrow templates, or you want to avoid your emails looking like everyone else's, that’s when custom design steps in. You get cleaner code, better rendering, and full control.

Bottom line

Drag and drop email builders are a good quick solution to your email design needs for lean teams, those of you who chase tight deadlines, or email isn’t a vital communication channel for you. On the other hand, investing in a custom email template design service makes more sense, if providing a premium and unique email experience is key to your marketing success.
