We'd love to learn more about your sending environment, where your outbound program stands today, and what you're trying to build, and give you an honest sense of whether Senders is the right fit.

Whether you have questions about how we work, want to walk through a specific challenge, or are just figuring out what production-grade outbound actually looks like in practice, we'd be happy to have that conversation.

Our Experience

We work with companies from a wide variety of industries, predominantly in the B2B sphere, but we don't play favorites.

SMB SaaS

You want to move upmarket, but enterprise inboxes don’t trust new senders. We help you build the reputation that opens doors beyond SMB.

Health and Medical

Heightened security around patient data means aggressive filtering—even for legitimate outreach. We help you land in inboxes that are designed to keep strangers out.

HR (Human Resources)

HR buyers sit inside large organizations with enterprise-grade filtering. Reaching them requires infrastructure that can survive that level of scrutiny.

Agencies

Your best prospects have the tightest defenses. Without production-grade infrastructure, you end up fishing where the filters are weakest—not where the clients are best.

Cyber Security

You’re selling protection, but your emails look like the threat. We build infrastructure that signals credibility to the systems you’re trying to get past.

FinTech

Trust is the product. Disposable domains and inbox sprawl undermine that from the first touch. We help you show up like the serious partner you are.

Momofuku

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.

• 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

Andrew Yeung

Where many others see a problem, Andrew sees an opportunity. His work may center around product leadership at Google (and previously Meta), but his true calling is all about bringing brilliant change-makers together.

• Andrew hosted small-scale dinners for a handful of people at the peak of the pandemic in NYC, to enable safe connections during the most isolating times.
• His events now count as many as 2,000 tech leaders each, and he has set up 100+ such parties for more than 15,000 people in the past couple of years.
• Andrew understands that if two minds are better than one, putting two thousand together, preferably in the same room, can make a profound difference.
• Given the impact of his community-building efforts, people want him to be able to reach out – and email is often the best way to do so.
• The Senders team made the necessary domain configuration adjustments, with a focus on the domain’s email authentication settings to enhance security and deliverability.
