8 Sales Questions You Should Never Ask a Prospect Over Email (And What to Do Instead)

As salespeople, we‘re always looking for ways to work efficiently and connect with as many prospects as possible. And in today‘s digital world, leaning heavily on email to communicate with potential customers is tempting. After all, firing off emails is fast, easy, and scalable. You can reach out to far more people than you could meeting face-to-face or even over the phone.

However, relying too much on email comes with serious downsides that can derail deals and damage relationships. When you hide behind email, you miss out on the human element that allows you to truly connect with prospects, understand their needs, build trust, and ultimately win their business.

In fact, research has consistently shown that live conversations are far more effective than email for moving sales opportunities forward:

• A study by RAIN Group found that sales winners have an average of 11.7 meetings with buyers, compared to only 3.6 for second-place finishers. Securing meetings is the #1 factor separating sales winners from the rest.

• An oft-cited stat from Gartner (formerly CEB) shows that the average customer is 57% of the way through the purchase process before engaging with a sales rep. But a deeper look at the data reveals that customers who engage with reps earlier in the process are more likely to buy and less likely to regret their decision. You can‘t engage early if you‘re relying on email.

• A report from CSO Insights found that phone and in-person meetings with decision makers have a 66.7% success rate, compared to only a 31% success rate for email.

The takeaway is clear: if you want to maximize your sales success, you need to get prospects on the phone and meeting face-to-face. Yet many reps still fall into the trap of asking pivotal questions and having sensitive conversations over email.

To help you avoid that pitfall, here are eight sales questions you should never ask a prospect via email, along with tactical advice for handling those moments over the phone instead:

1. "Do you prefer to communicate by phone or email?"

On the surface, this question seems respectful. Shouldn‘t we defer to the prospect‘s preferred communication style? But here‘s the problem: many buyers will default to email because it‘s low-pressure and low-commitment. It allows them to keep sellers at arm‘s length.

As sales expert Jeb Blount puts it: "You should use both phone and email in your pipeline management. However, you should never hide behind email out of fear or give your prospects a choice. Use the phone for the heavy lifting."

So when a prospect claims to prefer email, don‘t just accept that at face value. Acknowledge their preference but gently challenge it:

"I understand you prefer email and I‘m certainly happy to follow up that way. At the same time, I find even a short phone conversation allows me to understand a prospect‘s needs more fully so I can provide the most relevant information and avoid cluttering your inbox. What do you think about hopping on a quick 10-minute call this week so I can get a clearer picture of your priorities?"

2. "When would you like me to follow up?"

It‘s smart to get the prospect‘s buy-in on follow-up timing. But leaving it entirely up to them over email often leads to drawn-out timelines and lost momentum. Instead, get on the phone, discuss appropriate next steps, and propose a reasonable timeline.

If the prospect asks you to circle back in a few months, you might say:

"I appreciate you sharing your timeline – a quarter can definitely fly by! What do you think about getting a 20-minute meeting on the calendar now for mid-June? That way we can be sure to reconnect, and I‘ll be able to provide the most timely and valuable information based on our last discussion. We can always adjust if priorities shift. How does the morning of June 15th look for you?"

With this approach, you demonstrate respect for their timing while still proactively securing the next touchpoint. Aim to get that meeting booked before ending the call.

3. "Did you have a chance to review the proposal I sent over?"

We‘ve all been tempted to send this email. You put time and effort into a proposal, you‘re eager to get the prospect‘s reaction, and you want to keep the deal moving. But this follow-up comes across as pushy and self-serving when it lands in their inbox.

Plus, without live back-and-forth discussion, you have no idea how to interpret a short response like "It looks fine." Is that a brushoff? An objection in disguise? With no real-time dialog, you‘re left guessing.

A better approach is to schedule a phone meeting to walk through the proposal together:

"Thanks for the opportunity to put this proposal together. I‘ve attached it here, but I find it‘s most productive to review these live so I can walk you through the key points and rationale, and answer any initial questions you have. Could we book 30 minutes this Thursday or Friday to go through it together? Let me know what works best for your schedule."

Not only will this meeting allow you to thoughtfully present your proposal, it also provides a forum to surface and address concerns in the moment.

4. "Are you the decision maker on this?"

Discovering who holds power and how decisions get made is critical to navigating complex sales. But asking this over email is problematic for two reasons:

1. It‘s blunt and potentially off-putting. No one wants to feel like just a cog in the machine. Phrasing it this way fails to build rapport.

2. You‘re unlikely to get complete information. Organizational dynamics and decision making processes are often nuanced – an email response may only give you a piece of the puzzle.

Use live conversations to uncover the lay of the land more diplomatically. On your discovery calls, weave in questions like:

• "How does your evaluation process typically work for a solution like this?"
• "Who else would you recommend I connect with to fully understand the needs and priorities across the team?"
• "What‘s the best way for me to make sure all the key stakeholders have the information they need to make a confident decision?"

These open-ended questions feel more natural and conversational. And by discussing them live, you can gather richer context and ask follow-up questions in the moment.

5. "Why did you decide to go with a competitor?"

Losing a deal hurts. It‘s normal to want to understand why. But sending an email to dig for reasons will likely come across as sour grapes. You‘ll put the buyer on the defensive and they may hesitate to share the unvarnished truth, not wanting to burn a bridge.

If you want honest, constructive feedback, hop on the phone. Start the conversation by congratulating them on their decision and genuinely thanking them for including you in the process. Then transition to seeking guidance on how you can improve:

"I really enjoyed getting to know you and your team through this process. While of course I would have loved to partner with you, I‘m grateful for the opportunity to sharpen my skills and learn from the experience. If you‘re willing to share, I‘d love your candid feedback on what I could do better next time, whether that‘s in my communication, my solution, or anything else. I‘m always striving to improve and your insights would be really valuable."

By approaching with humility, empathy, and a growth mindset, you‘re more likely to get the honest input that will help you refine your approach in the future.

6. "Can you introduce me to [name] in [department]?"

We all know referrals and warm introductions are powerful for opening new doors. But a blunt email request like this feels abrupt and transactional, especially if you don‘t have a strong relationship with the person you‘re asking.

A savvier strategy is to use phone conversations to organically expand your connections within the account. As you‘re chatting live with your main contact, listen for openings and weave in natural questions like:

• "It sounds like the IT team will play a key role in rolling this new system out. What‘s the best way for me to connect with them to understand their perspective and technical requirements?"
• "Last time we talked, you mentioned [business goal] was a major priority for the executive team this year. Is that something your HR and Finance leaders are focused on as well? I‘d love to get their take on how the right solution could support those objectives."
• "As we move into implementation planning, who are the other stakeholders I should be bringing into the conversation? I want to make sure I‘m getting everyone‘s input and addressing any concerns upfront."

Not only will these questions help you gather valuable intel, they also position you as a proactive, thorough partner. The answers will often create a logical next step, like an informal intro or a joint meeting, without your contact feeling like you‘re just trying to ‘use‘ them to get to someone else.

7. "Any updates on this since our last conversation?"

It‘s important to keep close tabs on your opportunities. But a generic "checking in" email like this tells the buyer that the ball is in their court and you‘re just waiting around. It doesn‘t add value or give them any reason to engage.

Instead, use phone conversations to agree on clear next steps and timelines. At the end of each interaction, summarize the follow-ups and book the next meeting. For example:

"Here‘s what I‘m hearing for next steps: I‘ll send over that demo video and ROI calculator by end of day tomorrow. You‘ll review those materials with your team and get input from the key stakeholders we identified. Then, we‘ll reconvene on February 10th to discuss the feedback, answer any lingering questions, and hopefully get verbal approval to proceed with a proposal. Did I capture everything? Anything you would add or adjust?"

Not only does this approach keep everyone aligned, it also holds both parties accountable. With specific, time-bound action items, you won‘t need to chase the buyer or probe for random updates.

8. "Let me know if there‘s anything else I can do!"

This phrase gets tossed on to the end of sales emails constantly. And while the intent is positive, the execution is flawed. This line places all the burden on the buyer to figure out what they need and come back to you. Most buyers won‘t bother. As sales trainer John Barrows puts it, this is "the worst way to end any type of communication with a prospect or client. It screams: I‘m totally reactive, I have no idea how to help you, and I‘m just sitting around waiting for you to tell me what to do."

If you truly want to be helpful, get on the phone and make proactive recommendations. As the expert, you‘re in the best position to advise the buyer on how to solve their challenges and get the most value from your offering.

Your communication should sound more like this:

"Based on what you‘ve shared about needing to get new reps ramped up quickly, here‘s what I would suggest as next steps. We can put together an intensive 3-day bootcamp to cover all the key concepts, tools, and processes. Reps will come out of that ready to hit the ground running. From there, we‘ll layer on reinforcement through weekly coached role play sessions to hone their skills. And we‘ll provide ongoing access to our on-demand video training for microlearning in the flow of work. What do you think about that framework? I‘m happy to walk you through the specifics and customize it for your team‘s unique needs."

See the difference? You‘re not passively waiting for the buyer to make requests. You‘re proactively drawing on your expertise to recommend a path forward.

The Power of Human Connection

At the end of the day, sales is about relationships. Your ability to foster genuine, trust-based connections plays a huge role in your results.

Consider these findings from Sales Insights Lab:

• 60% of buyers say that the sales rep has a high impact on their purchasing decision
• 95% of buyers are more likely to buy when the sales rep demonstrates high levels of active listening
• 71% of buyers want to work with sellers who collaborate with them

Stats like these underscore why defaulting to email is so risky. No matter how thoughtfully composed, an email can‘t compete with the rapport-building power of a live conversation. Over the phone or face-to-face, your personality shines through. You can demonstrate empathy, pick up on subtle cues, dig deeper into their responses, and make a real human connection.

Of course, this doesn‘t mean you should never use email. Email is great for quick follow-ups, sharing resources, and finalizing logistics. But when it comes to substantive conversations that could make or break the deal, pick up the phone.

And it‘s not just your close rate that will benefit. Touching base regularly with your prospects deepens the relationship. You stay top of mind. You‘re continuously uncovering new information. You spot red flags earlier. Deals are less likely to go dark.

Yes, live conversations take more effort than firing off an email. But that effort pays off in more pipeline, more closed won deals, and more satisfied customers who stick around for the long haul. And that‘s what great selling is all about.
