Digital Marketing Review from Peter Bronsnick
Splendor has been an amazing partner. Their creativity, conceptual design and execution have been instrumental in bringing our properties to market and are a key factor driving the success of our efforts.
Digital Marketing Review from Eric Millard
When assisting us in rebranding our company and redesigning our website, Splendor invested significant time in really getting to understand our business and its nuances, what makes us unique, and what our value proposition is. The results were fantastic – clear and accurate messaging, excellent design, and a foundation. CS Energy’s revenues increased 20% in the year after our rebrand and we have recently been recognized as one of the nation’s top 10 companies in our industry. We attribute much of our recent success, particularly in attracting and retaining new customers, to Splendor’s great work.

Web Design Review from Celyn Matienzo
Working with the Buzzworthy team on a website design and development project has been a fantastic experience with the expertise and creativity they bring to the table. Anyone can design and develop a basic, functional site that looks good. But the Buzzworthy team doesnt just take orders and pull something together that just meets what you think are your basic requirements.The team took the utmost care to get to know what makes our products and services unique so they could create a visually compelling website that communicated our key value proposition to help us stand out in a crowded market. The page layouts, visual elements, and even the smallest details on the site all work together. It takes true mastery of their craft to balance visually stunning sites with functionality both in technical execution and as a part of an overarching sales and marketing strategy.Buzzworthy is truly a valuable collaborative partner that wed be glad to work with again on future projects!
Web Design Review from Craig Yeomans
The whole Buzzworthy team was attentive to our wants and needs, and integrated our vision into the site design in a way that was so much better than we had ever hoped it could look. This is a very important cause to us and the team at Buzzworthy treated it with the care it deserved and delivered enormous value with an absolutely gorgeous website. I would recommend them to anybody!

We purchased the personal injury lawyers email list from TargetNXT for our legal marketing campaigns. The results were significant resulting in good response rate, higher engagement and increased lead volume. The support team was quick to respond and guided us throughout the process.
ahmed labib's Review Sourced from Google
The Physicians Email List we purchased from TargetNXT has positively impacted our lead conversions. Since we were looking for bay area physicians in several specialties, their geo-segmented data enabled us to pinpoint our targeted customers. Because of this we were able to generate a large amount of high-quality leads that have uplifted our business growth. The support we got from TargetNXT’s team was commendable and we are looking forward to work with them in the future as well.

We paid $1,336 for a particular list of 1,336 companies. Of those 1,336 companies 1,045 were not relevant and 82 of them simply did not exist. From the time of payment these guys took 4 business days to "validate" the companies before sending us the list and they still managed to send 82 companies that do not exist. They also refuse to refund the $82 we spent on these companies that do not exist, instead offering to send more companies. Do not do business with these people.

Code Crew has been a game-changer for our email campaigns—every design they roll out feels like it was tailor-made for our brand (because it basically is). Their knack for understanding our voice means we never worry about tone or consistency. Communication is a breeze; they’re quick to respond, proactive with ideas, and never leave us guessing. Honestly, partnering with them has made sending emails something we actually look forward to.

CodeCrew is amazing! From day one, they understood our brand, and they got to work on creating email campaigns and flows for our company, with minimal oversight. The team is extremely professional, reliable and dedicated. I recommend CodeCrew to any company looking to boost email marketing!

For the past 20 years, our company has been honored to help some of the world's best firms restructure sales and marketing divisions.We had engaged Alliance Interactive to redesign a 200-page website with functionality improvements; the scope of work was massive.At the time, our website ranked well and with sufficient conversion rates, but it needed to be modernized.However, it was imperative that conversion rate, branding and search engine results be maintained.Therefore, we began looking for digital marketing companies to assist with a complete redesign.For context, we budgeted about $35,000 for the website redesign and overhaul project. Therefore, we had many digital marketing firms to choose from.After interviewing about a dozen, we ended up choosing Alliance Interactive. They blew away expectations.Our project manager was extremely smart and innovative. He learned our business advantages very quickly and made great suggestions. Alliance Interactive made our site look very creative, yet kept it user-friendly.The visual layout was artistic, yet professional. We could not have been happier. Very smart investment on our part and thank you to the Alliance Interactive team.

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:

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.
