SEO Review from Brendan Staunton
We needed a new website that kept current links while optimizing the content and design and improving SEO. They came back first with designs that we approved or disapproved. Then we received a final design we liked over the course of 4 meetings. After that, they started on the development process which proceeded smoothly. Then they worked on the SEO. They could implement all of our requests into the design. With the outcome given to us by Fahrenheit Marketing, we have seen massive productivity.

eCommerce Development Review from Undisclosed
We have been working with First Pier for almost 10 years now, beginning with the launch of our women’s boutique E-Commerce business. First Pier has been responsible for our e-commerce store design, web development, e-commerce SEO, digital strategy, online marketing campaigns and beyond ever since. As a already successful brick and mortar retailer, we saw an opportunity to reach beyond our existing customer bases in Portland, Maine & Portsmouth, New Hampshire by creating an online shopping experience accessible 24/7 and nationwide. First Pier has helped us turn that vision into reality by taking us from no online store and zero sales to a dependable thriving new channel for our business that continues to grow. Our experience with Shopify started when First Pier migrated our site from Magento to a Shopify website. Since First Pier is a designated Shopify Expert, we knew we could trust them with the daunting task of moving all of our products, accounts, and customer history to our new Shopify site. They made the transition to a new e-commerce system painless by ensuring our hands were held along the way, we were thoroughly trained, and none of the SEO ranking keywords were lost. We continue to work with First Pier on expanding our use of Google Shopping SEO and will be implementing Shopify’s Point of Sale in the coming year as part of a continued effort to deliver a unified customer experience at our stores. As a small women’s boutique based in Maine, we are now able to deliver our customer experience to tourist and seasonal customers where they are year round. We would recommend First Pier to anyone looking to build or update a Shopify store.
Shopify Review from Undisclosed
First Pier has been so helpful with the transition to shopify. After initially setting it up they provided us with great documentation on how to use the site and they've continued to support us through any issues that arise.
Shopify Review from Undisclosed
First Pier helped us move, update, and launch our online business on Shopify. As a high-traffic bakery, it was important to us that customers buying from around the country were able to view the quality of our products, feel the vibe of our Portland and South Portland shops, and trust that their order would be as special as a visit to our Maine bakery. First Pier delivered mouth-watering e-commerce product photography, an easy-to-use site, and supported us every step of the way. Our shoppable site is now optimized, accurately reflects our brand, and has poised us for growth.

Advertising Review from Damian Ross
I worked with WKND Digital for 9 months. During the first 2 months they had the A team on the job, but after they failed to beat our current ROI Benchmark or Scale, they foisted us on the B and then the C team. The result was even worse results, tripled delivery times and stopped sending us creative for review. We later discovered the creative had misspelled and was way off message. Yes they're suing (2 years later) me because I canceled in November 2021 and they want to get paid for 12/21.

The WKND team not only helped us position our online store in the competitive water filtration market but also optimized our business operations beyond just marketing. We now have an amazing, streamlined system that’s been working great for the past 2 years. We’re still working with them and couldn’t have picked anyone better. While we wasted a lot of money with other companies in the past, these guys were the only ones who truly cared and helped our company grow as planned.

Email is the leading channel for securing leads, nurturing them, and a close second for converting them. It is also an integral part of the entire sales process, not just the early stages of content marketing.
Statistics show that nearly 4.5 billion people worldwide used email in 2025, and this number is projected to reach over 4.8 billion by 2027. This scale is one of the main reasons email marketing companies continue to deliver strong, measurable ROI across industries.
Out of all marketing and advertising channels, email accounts for 39% of usage, making it one of the top 5 most used channels, right after social media marketing with 52%, social media ads with 47%, and search advertising and SEO accounting for 40% and 39% respectively.
According to the ZeroBounce report, 93% of people use email every day, and many say it actively improves their shopping experience. For businesses working with email marketing firms, this daily engagement creates consistent opportunities to influence purchase behavior:
While having a catchy subject line is important, it’s only the second reason why people open your messages, the 2025 email marketing statistics reveal.
According to reports, 46% of people open their inbox regularly to check relevant emails, while 43% open it because of a catchy subject line.
21% said they open emails regardless of the content.
Only 14% interact with their inbox out of fear of missing out, and 7% presented other reasons for checking their emails daily.
Experienced email marketing agencies use open rate, click rate, delivery rate, unsubscribe rate, and bounce rate metrics to evaluate campaign health, engagement quality, and long-term list performance.
Open rate measures the percentage of recipients who open an email and reflects subject-line effectiveness and sender trust.
Average open rates typically range from 15% to 25%, though reliability has declined due to Apple’s Mail Privacy Protection.
Best practices include personalization, keeping subject lines under 40 characters, and A/B testing.
Click-through rate (CTR) tracks engagement by measuring clicks divided by emails delivered, while click-to-open rate (CTOR) measures clicks divided by opens.
A healthy CTR is usually 2%–3%.
Personalization is crucial, as 40% of respondents report frustration with irrelevant content, and emails with visuals can increase CTR by up to 300%.
Delivery rate indicates how many emails are successfully accepted by inbox providers.
The goal for everyone is to reach a 100% deliverability rate, but that’s usually unattainable because many emails end up in spam folders that users often don’t filter through.
With an expert B2B email marketing agency, you can expect to reach a 99% deliverability rate, assuming it follows best practices.
According to the ZeroBounce survey, 78% of users mark an email as spam if the email "looks like spam".
So, even if it doesn’t immediately go to the spam folder, an email will not be considered successfully delivered when the user doesn’t get to it.
As of 2024, Gmail and Yahoo require authentication (SPF, DKIM, DMARC) for bulk senders, making deliverability a shared responsibility between senders and ESPs.
Unsubscribe rates under 2% are considered normal, as Campaign Monitor suggests.
Segmentation, personalization, preference centers, and re-engagement campaigns for contacts who have been inactive for 6+ months help reduce churn.
Bounce rate should stay below 2% and include soft bounces (temporary issues) and hard bounces (invalid addresses).
-content-webp.webp)
Double opt-in, list hygiene, segmentation, and secured signup forms (e.g., reCAPTCHA) are key to maintaining list quality.
It's more effective than it’s been in years, according to Omnisend’s 2025 eCommerce marketing report, which shows global email open rates increased 6% year over year, reaching 26.6%, marking the fourth consecutive year of growth.
This sustained increase suggests that consumers are actively engaging with it, especially when messages are relevant and timely. This is why many brands continue to invest in trusted email marketing providers to manage performance at scale.
Click-to-conversion rates grew by 27.6%, indicating a shift in consumer behavior where people are clicking less impulsively, but when they do click, they’re far more likely to purchase.
In other words, email is attracting higher-intent, more purchase-ready traffic.
The revenue impact becomes even clearer when looking at automation.
The report found that automated emails generated 37% of all email-driven sales while accounting for just 2% of total email volume.
One in three people who clicked an automated email made a purchase, compared to one in 18 for scheduled campaigns. This highlights how modern email success is driven by strategy and timing, not sheer send volume.
Email also benefits from being a first-party channel, giving brands direct access to their audience at a time when paid media costs are rising, and third-party data is becoming less reliable.
With growing engagement, stronger conversion efficiency, and unmatched ownership of customer relationships, email remains one of the most reliable and scalable marketing channels in 2025, especially when paired with automation and lifecycle targeting.
We have created a list of agencies for you to choose from based on the three different budget ranges they’re offering:
| High budget: $50,000+ |
|
| Mid budget: $25,000-$50,000 |

| Low budget: $10,000-$25,000 |

You can expect to get $36 for every $1 spent on email marketing, achieving a 3600% ROI.
According to an Omnisend report, buyers who click automated emails convert at a rate of 1 in 3, compared to 1 in 18 for scheduled campaigns, highlighting how strategic automation dramatically improves returns.
Email remains the top revenue-driving owned channel. The Omnisend report also found that automated emails generated 37% of email-driven sales from just 2%of total email volume, outperforming both SMS and push notifications in overall revenue contribution.
Email automation is the single biggest revenue lever in eCommerce marketing. Omnisend’s report shows automated messages outperform campaigns with:
This is why top email marketing agencies prioritize automation before increasing send volume.
They typically use a wide range of email service providers (ESPs) and marketing automation platforms, depending on the client’s size, industry, and technical needs.
