Best AI SDR Quality: 7 AI SDR Apps That Send Messages Your Prospects Will Answer

Not all AI SDRs are created equal.

Some can draft and send emails on autopilot, but that doesn’t mean the messages will be good enough to get prospects to answer.

The best AI SDRs craft messages that feel human, are relevant, and arrive timely, increasing your chances of getting a response.

Here’s a closer look at the message quality of 7 leading AI SDR apps.

What makes a great AI SDR email?

If you’re weighing an AI SDR for lead generation and outreach, message quality should be a top priority. A well-crafted email can spark conversations and build relationships, while a poorly written one can do more harm than good.

Many platforms rely on the “spray and pray” model – blasting the most messages to as many leads as possible, only achieving results through sheer volume (after all, if you roll a d20 often enough, you should land on a “natural” 20). 

The downside is that low-quality outreach carries the risk of burning your total addressable market, as well as damaging your email infrastructure and brand reputation. Over time, this makes it harder to find new leads or break into new markets.

This has led to growing skepticism about AI SDRs as a whole.

But not all AI SDRs send bad emails that don’t convert. The key is knowing what makes a great AI email and which platforms can deliver.

Clarity & relevance

No one likes generic emails that are like a shot in the dark, hoping to catch a lead’s attention without prior research. Each email should be adjusted to the lead’s buyer intent and address their needs, pains, and interests. 

When scoping out AI SDR tools, you’ll want to ask how they collect and work with sales data. 

For instance, in addition to a ZoomInfo integration and other data providers, AiSDR pulls data from your HubSpot and LinkedIn.

Personalization

You should also ask how the platform personalizes its messages. 

For best messaging, the AI SDR should be capable of using various intent signals for personalization, such as:

• Recent funding rounds
• Hiring intent
• New hires
• Product champions
• Recent mentions in the news
• Technology stack
• Search queries
• LinkedIn engagement 

AiSDR allows you to find prospects that match your ideal customer profile through standard database filters and AI-powered prospecting. AiSDR then uses this information to send messages when prospects have an appetite for your solution and adjust message content for greatest impact.

Style

A great email grabs a lead’s attention without sounding robotic or generic. 

But while personalization is key to getting a response, so is using the right structure to guide your messaging.

Instead of falling for the trap of using templates for mass email outreach, consider email frameworks.

While templates have their uses, such as webinar invites and follow-ups, frameworks offer a flexible structure for crafting first-touch emails, allowing for more natural personalization and tailoring to prospects. Rather than filling in blanks, you’re shaping a message that feels authentic.

Here’s a quick look at an email written by AiSDR for a customer.

Here’s what makes this email pop:

• The first sentence is fully about the recipient and their product. It’s not about superficial personalization when you just insert the recipient’s name and company and call it a day.
• The email focuses on the prospect’s pain point. 
• The email doesn’t sound salesy and focuses on the product’s benefits.
• It ends with a personalized and relevant touch, leaving a pleasant aftertaste.

And this email did get a meeting booked for the client.
