SmartSites impressed me from day one. They are knowledgable, kind, and most importantly keep things simple and streamlined so that even an SEO-newb like me can understand. Tiffany and Luna are my main points of contact and they are especially great! I would recommend to anyone looking for an agency to really take their website and digital presence to the next level.

At first, a survey was conducted to gather company background, product information, target markets, etc. Next, accounts were established on various Google Business platforms, social media, etc. Then SmartSites created the ads and campaigns, and we were off and running in just a few weeks.

Right after launching our campaigns with Disruptive, we saw results almost instantly. Our monthly revenue jumped from about $50,000 to over $70,000. Every key Google Ads metric improved, and by November, we were already nearing $550,000 in revenue, well on track to hit our $700,000 annual goal.

What services do email marketing agencies provide?
They offer a suite of services that help businesses engage audiences, drive conversions, and measure email marketing campaign performance.
Email marketing strategy and planning: Developing end-to-end email strategies, from audience targeting and segmentation to campaign calendars and lifecycle planning (e.g., welcome series, promotional campaigns, re-engagement flows)
Email campaign creation and management: Designing email templates, writing copy and subject lines, and setting up campaigns with proper personalization. According to Litmus, newsletters remain one of the most common email types, used by about 68% of marketing teams in email programs, making it a staple service for many email marketing firms.
Marketing automation: Around 50-71% of businesses use drip sequences, triggers, and customer journeys. Email marketing firms help set up and optimize these workflows for better engagement and efficiency.
List growth and segmentation: Splitting lists by behavior, purchase history, or demographics is critical for relevance. Segmented campaigns can generate up to 760% more revenue than non-segmented campaigns, according to NPD Group. Â
Deliverability and inbox optimization: Monitoring sender reputation, spam filters, and domain authentication (e.g., SPF, DKIM) to improve inbox placement, by reducing bounce rates and helping more emails actually reach subscribers.
A/B testing: Running A/B tests on subject lines, content blocks, layout, and send timing to boost engagement metrics like open rates, CTR, and conversions. Agencies test multiple email template variations through A/B testing.
Analytics and reporting: Providing dashboards and insights on open rates, click-through rates (CTR), conversion rates, and revenue attribution help clients measure ROI and refine future campaigns.Â
When should I hire this agency?
Hire an email marketing agency when your internal efforts aren't delivering the results you need, and you need to boost performance, save time, and improve ROI. Many small business owners begin with a free plan and basic campaigns, but hire an agency once email becomes a core revenue channel.Â
More specifically, you should hire an email marketing firm when:
Your key email metrics, such as open rates, are significantly below 30-40%, or your click rates are under 2%.
ROI from email is lower than expected compared with channel standards; the average ROI is around 3600-3800% (about $36-$38 return for every $1 spent).
The internal team is stretched thin or inexperienced.
You lack advanced capabilities like email marketing automation, segmentation, or personalization.
You're currently using a free plan from your email platform, and you've hit subscriber limits, maxed out monthly send caps, and lack advanced automation features.
You want measurable revenue growth.
How much do email marketing companies charge for their services?
The cost varies widely, depending on experience level, services included, list size, and campaign complexity. Email marketing firms usually charge $15 to $300 per hour, depending on the agency's expertise and location.
Basic to mid-level agency: $1,000-$3,000/month for smaller businesses or limited campaigns.
Standard full-service range: $2,500-$10,000+/month for ongoing work, including strategy, email automation, and reporting.
Specialized email marketing services: $1,500-$3,000/month for 2-3 campaigns or $5,000- $15,000/month for enterprise-level management.
High-end retainers can exceed $10,000/month when they include advanced segmentation, data integrations, or multi-channel automation.
Per Email or Per Project
Per email: Roughly $250-$700 per campaign/email created.
Per project: Starting around $1,000+ for a defined one-time engagement.
While free plans allow businesses to start email marketing at no cost, they typically limit the number of contacts, automation, and advanced analytics. Agencies, by contrast, focus on revenue optimization, making them a growth investment rather than a cost.
What should I look for when hiring an agency?
When choosing an email marketing firm, focus on measurable performance, strategic capability, and transparency. Here are the key criteria to consider:
Demonstrated performance results Top email marketing agencies will show measurable outcomes, so look for case studies that include revenue lifts, conversion improvements, or ROI figures. Email marketing typically delivers $36 in revenue for every $1 spent, so agencies should tie results to actual financial impact.
Baseline benchmarks and gap analysis Email marketing companies should compare your performance to current benchmarks and explain how they plan to improve your metrics.
Segmentation and personalization expertise Segmented campaigns can see up to 760% more revenue than non-segmented ones, and personalized subject lines can boost open rates significantly. Look for clear segmentation strategies aligned with buyer behavior.
Automation and lifecycle strategy Automated flows such as welcome series, cart abandonment, and post-purchase messaging are proven winners: automated email campaigns often outperform basic sends with higher opens and conversions. Choose an agency that builds and optimizes automation workflows.Â
Data-driven measurement and reporting A B2B email marketing agency should establish KPIs, including conversion rate, revenue per recipient, and list growth, and report them regularly. Avoid vendors that focus only on vanity metrics like opens without linking to business outcomes.Â
Testing and optimization process Continuous A/B testing should be part of their execution plan, as it's essential for growth over time.Â
Technical and platform expertise Ensure the agency knows your email platform, be it Constant Contact, Klaviyo, Mailchimp, or HubSpot, and fundamentals like deliverability, authentication, compliance, and list hygiene.
Transparent scope and pricing Know what email marketing services are included and what costs extra before you sign. Clear deliverables, timelines, and reporting expectations avoid surprises later.
What factors affect an email marketing firm’s pricing?
Email marketing company prices are influenced primarily by:
If a business is still operating on a free plan, agency costs may initially include email marketing platform migration, list restructuring, or automation setup, which can increase onboarding pricing.
By understanding these factors, businesses can better compare proposals and choose an agency whose pricing matches the value and outcomes they expect.
