There's a lot of really really awesome things. I would say the team is just very open for us. Testing things out - different segments, different copy and they turn around time is just very, very quick which I really, really appreciate and that's been consistent since day one.

Sending a few emails here and there is easy -- sending at a consistently high volume and having them delivered every time is really really hard. Senders handles that for us in spades.

Founded by chef David Chang, Momofuku is a renowned culinary brand with a nation-wide presence, including restaurants and an online store with delicious goods. They ran into an issue with their email sending – high bounce rates and blocked sending.

With hundreds of thousands of people on their email lists eager to stay informed, and an impeccable reputation to uphold, Momofuku wanted to nip this problem in the bud quickly.

  • Momofuku reached out to Senders to run a diagnostic test on their sending infrastructure and find the root cause
  • Senders deliverability experts discovered an issue with their DMARC, which was preventing emails from being sent, as their WordPress wasn't aligned with their SPF
  • Senders provided the most effective solution helping Momofuku restore safe sending, and suggested next steps to ensure everything keeps running smoothly on their end
  • The client reported that Senders helped identify the problem and got them back on track 

Up for coffee with a health kick, sans the jitters? Try Everyday Dose – a brand on a mission to provide coffee lovers with a healthy alternative packed with all kinds of goodies. The Founder, Jack Savage, learned through personal experience that we needed an option that doesn’t lead to a slew of possible side-effects. That’s how this mushroom-based blend with nootropics and collagen protein came to be, helping boost focus, energy, and reduce stress in one go.

The Everyday Dose team prides itself on excellent customer support, in addition to their delicious set of products. So when they spotted DNS propagation issues setting up their customer experience platform, they reached out to Senders to find the best way to sort it out.

  • Senders deliverability experts confirmed the problem the team at Everyday Dose initially diagnosed
  • To enable healthy DNS propagation, the Senders team helped clean their DNS registrar of old DNS records that were causing issues with propagation
  • The client reported they were now able to set up their DNS correctly, enabling them to run their platform smoothly

While many follow the latest marketing fads, there are businesses that support their clients with impactful, data-driven strategies for long-haul success. One such business is Influence to Action, creating sales, marketing, and leadership strategies that provide lasting value to growth-centric B2B companies. Both their turnkey and “done with you” services are built to ensure measurable, tangible results, and come with ample flexibility to adapt to the company they’re meant to serve.

Naturally, they wanted to make sure their email sending infrastructure was set up correctly, to protect their reputation and successfully reach their recipients. Our deliverability team worked with the client’s team on:

  • Aligning the client’s three domains with Amazon to make sure they are compatible and optimized in order to integrate with Amazon’s system.
  • Setting up a proper DMARC policy to protect their domains against unauthorized use and phishing scams.
  • Enhancing email deliverability as well as security, so that each email sent from these domains can be properly authenticated and more likely to land in the right inbox.
  • As a result, the client can protect the reputation of their business and domains, while safely sending out their email campaigns.

Sometimes the sheer number of options of any product can be daunting – how on earth do you pick the right one? This is especially true with supplements, as we can find them just about anywhere, but we can rarely understand a third of the ingredients listed. Unlike most, Physician’s Choice provides supplements with pure, potent ingredients that work. No fillers or “proprietary” blends with unidentified ingredients. They do the research, so you don’t have to.

Integrity and transparency are part of their core values, so when their team ran into sending issues, they were referred to Senders.

  • The client’s team spotted issues with DMARC failures in Google Postmaster
  • The Senders deliverability team worked with the client to update the DMARC configuration to enable report collection
  • The client is now able to obtain detailed reports to diagnose the exact causes of the failures and prevent them in the future with proper DMARC setup
