Your call-to-action can make or break your cold email. You can have great copy, a tight hook, and the perfect recipient—but if your ask is wrong, you'll get ignored.

Here are three types of CTAs, when they work, and when they don't:

1. The “Call" CTA

Example: "Are you open to a call next week to walk through how this might work for you?"

When it works: When you've already established some credibility—maybe they've seen your content, or you referenced something ultra-specific to their business. The ask feels low-risk because they already have a sense of who you are.

When it doesn't work: When you're completely cold and your value isn't immediately obvious. Asking for a call too early just gets you a "no" (or silence).

Pro tip: If you're using this CTA, make sure your email includes concrete proof of what you've done for similar companies or what they might learn from the call. "We helped a medical device distributor cut their sales cycle from 90 to 60 days and I’m happy to walk you through exactly how we did it when we talk" is way more compelling than "we help companies close deals faster."

2. The "Forward This" CTA

Example: "If this isn't your area, mind pointing me to whoever handles [specific thing] on your team?"

When it works: When you're reaching into an org where titles are fuzzy, or you're genuinely unsure if you've reached the right person. This CTA keeps the door open without forcing a decision.

When it doesn't work: In some orgs where people protect their time aggressively. You'll just get ignored. Also doesn't work if your email is generic—why would someone forward a vague pitch?

Pro tip: Make your email so specific and relevant that forwarding it actually makes the recipient look helpful. "Thought this might be useful for your ops team" only works if it actually would be useful.

3. The "Let's See If This Fits" CTA

Example: "I'd love to show you a quick demo—takes about 15 minutes and we can both decide if it makes sense to keep talking."

When it works: When your offer is complex or high-ticket and needs some explanation, but you still want to keep the pressure low. This CTA frames the call as mutual evaluation, not a hard sell.

When it doesn't work: If your offer is simple or transactional. Don't ask for a demo call to sell a $300/month service—just explain the value and ask for a reply.

Pro tip: The key word here is "both." You're signaling that you're qualifying them too, which paradoxically makes them more interested. People want what's not being forced on them.

Bottom line: Match your CTA to where the recipient is in their awareness of you and their problem. Too aggressive, and you scare them off. Too passive, and nothing happens. Get it right, and you'll see your reply rates jump.

We’d love to learn more about your business, email deliverability and outreach goals, and see if we might be able to help.

Senders Case Studies

See All Case Studies

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. 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 

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.

How it started: 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. How it’s going: 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. So, we helped out a bit.

  • Andrew came across deliverability issues that prompted him to get in touch with Senders and look into the best possible solutions
  • The Senders team made the necessary domain configuration adjustments, with a focus on the domain’s email authentication settings to enhance security and deliverability
  • The SPF record was updated to include “Brevo” (Sendinblue) to strengthen authentication and reduce the chance of landing emails into spam
  • The DMARC policy update enabled better readability of DMARC reports for human analysts, which is essential for preventing email spoofing and phishing
  • Senders fixed the missing DKIM setup with Google, so that it now shows the email hasn’t been tampered with in transit
  • As a result, the client now has better, more stable email deliverability and security

Myrina.ai

Stands out as a trailblazer in empowering women entrepreneurs through technology and a supportive community.

Myrina.ai offers a cutting-edge range of AI-powered SaaS marketing and sales tools that cater specifically to female entrepreneurs and women-led businesses. Myrina.ai enables users to automate marketing and sales, while helping them scale their authentic selves while saving time and boosting conversions. Their Myrina’s Army community fosters a supportive platform that champions female entrepreneurs and their values, empowering them to conquer barriers and achieve their business goals. The company's dedication to providing not only top-notch technological solutions but also a platform for networking and mentorship underscores their commitment to fostering success among women in the entrepreneurial space.

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

Physician’s Choice

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.

  • 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
