Most fast-moving ecommerce and SaaS teams eventually hit a wall with email. You either don’t have the time, the right email marketing tools, or the specialized expertise to unlock its full potential. And patching it together—sending a few email campaigns when you can, letting automations limp along—won’t cut it in 2025’s cutthroat inbox.

The smart solution here is to outsource email marketing—but not in the old-school way with expensive, bloated agencies that move slow and charge faster. Instead, you can hand it off to proven experts who can own the strategy, write killer emails, build high-converting flows, and get results fast.

But when does outsourcing email marketing services make more sense than relying on your in-house team?

When to outsource email marketing

Your email list is growing, but sales aren’t

If your subscriber list is ticking up but your revenue from email isn’t, you’ve got a leak—and it’s bigger than you think. 

Good email marketing moves people to act. And that requires the right messaging, the right timing, and the right flows—none of which happen by accident. If you’re just "sending the occasional newsletter," you’re sitting on untapped profit. A dedicated email marketing specialist can turn that list into real revenue and boost your email marketing efforts.

You’re too busy to focus on email

Email marketing strategy, copywriting, design, segmentation, A/B testing, deliverability monitoring—it’s not something you squeeze into a Friday afternoon between meetings. If these email marketing tasks are competing with a dozen other priorities, outsourcing lets you hand them off to someone who can give it the attention they deserve.

Your open and click rates are dropping

If your email metrics are tanking, it’s rarely a random fluke. It usually points to bad segmentation, poor deliverability hygiene, and rushed, irrelevant content. An experienced email marketer will audit your lists, refresh your content, and rebuild momentum.

You’re missing easy revenue

Automations like abandoned cart emails, upsells, and reactivation campaigns can quietly drive serious revenue—but only if they’re set up and optimized. Outsourcing to the right marketer will not only plug these revenue holes but will turn them into some of the highest-ROI channels in your business.

You lost your email person

Maybe your email marketing service provider quit. Maybe your digital marketing freelancer vanished. Either way, if email suddenly loses its owner, outsourcing will immediately fill the gap with someone experienced and keep your programs running strong without a long hiring process.

You’re scrambling for a launch 

Launching a new product, feature, or promotion? Great. But if you don’t have dedicated resources working on your email sequences now, you’re already late. A skilled email marketer will map the full customer journey—pre-launch, launch day, and post-launch—plus build out the automations, creative, and testing needed to maximize every single send.

What to look for in an outsourced email marketer

Here's exactly what to look for when outsourcing email marketing if you want someone who will make a real impact:

Strategy + execution combo

You don’t need someone who just "sends emails." You need an email strategist who can build the entire customer journey and execute it. A real email marketer knows how to nurture new subscribers, turn them into buyers, re-engage lapsed customers, and maximize lifetime value.

What to ask:

  • Can you map out a full lifecycle journey with automations, not just one-off email marketing campaigns?
  • How do you balance short-term wins (like promos) with long-term engagement (like nurture flows)?
  • How do you segment audiences based on where they are in the customer journey?

💡 Red flag: If all they talk about is "sending campaigns," not building systems that scale, walk away.

Copy and design skills

Words and visuals are the first things your customers see. If your emails don't look right and sound right, they won't even get read, let alone drive action. You need someone who knows how to write to convert and design to build trust immediately.

What to look for:

  • Can they write strong subject lines, preview text, and body copy that drive opens and clicks?
  • Can they create layouts that are mobile-first, easy to scan, and visually aligned with your brand?
  • Are their emails accessible (e.g., readable fonts, alt text for images)?

💡 Pro tip: Ask to see real examples. Not just templates—actual effective campaigns they wrote and designed. Bonus points if they can explain why they made certain creative choices.

Platform expertise (Klaviyo, Mailchimp, HubSpot, etc.)

Anyone can set up a basic email blast. You need someone who knows how to squeeze every bit of performance out of your platform. Plus, understands how to optimize every touchpoint inside it.

What to check:

  • Are they fluent in your platform—or the one you’re moving to?
  • Can they build and optimize flows like abandoned carts, win-backs, and welcome series?
  • Do they understand email deliverability (SPF, DKIM, DMARC, sender warming)?
  • Can they pull and interpret platform reports (not just open and click rates, but deeper engagement metrics like revenue attribution and flow performance)?

💡 Pro tip: Look for platform certifications (like Klaviyo Expert or HubSpot Email Marketing Certified). At a minimum, they should be able to explain advanced platform features without fumbling.

Test-and-iterate mindset

Email marketing isn’t a “set it and forget it” channel. What worked last month might flop next month. A strong email marketer embraces data and constantly tests and adjusts to secure better results.

Here are the signs of a real test-and-iterate marketer:

  • They build campaigns around clear hypotheses and measurable business goals.
  • They A/B test subject lines, send thnb v4r∂s∂za4imes, calls-to-action (CTAs), layouts—and use the results to improve.
  • They monitor open and click rates, conversion rates, revenue per send, and customer lifetime value (LTV) driven by email.

What to ask:

  • Tell me about a test you ran that surprised you. How did you react?
  • How often do you update and optimize automations?
  • How do you prioritize what to test first?

💡 Warning sign: If they can’t name a recent test they ran or insights they learned, they're likely just pushing emails out on autopilot—and that’s a fast track to stagnant performance.

Email outsource options compared: agency vs. freelancer vs. platform

When you’re ready to outsource email marketing, you’ve got three real options: an agency, a freelancer, or a talent platform like MarketerHire. Each one works, provided you pick based on your real needs.

Agency

Best if you need a full-service partner handling everything—digital marketing strategy, copy, design, reporting—at high volume. But get ready to pay for it. Agencies come with expensive retainers, longer onboarding times, and extra layers between you and the person doing the work. You’ll get polish, but you’ll sacrifice speed and direct control.

Freelancer

Best if you want flexibility and lower costs. You can find strong freelancers to knock out specific projects like new flows or template refreshes. The catch? Vetting is all on you. Hire wrong, and you’ll burn time, budget, and momentum trying to fix it.

MarketerHire

Best if you want fast, proven talent without agency markups or endless hiring processes. You still work directly with your marketer—they’re part of your email marketing team who use internal resources, not a third-party vendor—but you skip the long contracts, bloated fees, and hiring headaches.

Option Best for Weaknesses
Agency Full-service, high-volume email programs where you need strategy, creative, and execution bundled together. Expensive retainers, slower ramp-up times, often less agile with changes.
Freelancer Cost-effective, flexible projects where you need hands-on help for successful email marketing campaigns, flows, or audits. Risk of hiring someone without the right skills or strategic experience; more management overhead.
MarketerHire Teams that want a proven email expert matched fast—someone who can own strategy and execution without agency bloat. Requires a little more hands-on collaboration compared to outsourcing 100% to an agency.


To put things into perspective:

  • Work with an agency if you want a big bundled solution and cost isn’t a dealbreaker.
  • Opt working with a freelancer if you have the time (and stomach) to manage and vet carefully.
  • Hire email marketers through MarketerHire if you want top-tier results, fast, without the drama.
