Last updated on

PS

Apollo and Klenty serve different segments of the sales engagement market, with Apollo excelling in data quality and ease of use, while Klenty offers broader channel support. Apollo is better suited for teams prioritizing data accuracy and simple workflow creation, particularly those needing a robust prospecting database integrated with their engagement tool.

Klenty, on the other hand, is ideal for mid-market businesses requiring multi-channel outreach capabilities including SMS and WhatsApp. Apollo's standout features include its superior contact database, email warmup capabilities, and intuitive sequence builder, while Klenty differentiates itself with broader channel support and parallel dialing capabilities.

Advantages of Klenty

Klenty offers better sequence automation capabilities than Apollo
Unlike Apollo, Klenty provides task and reminder automation, allowing sales teams to automatically assign tasks when prospects take specific actions. This automation capability is particularly valuable for larger sales teams looking to maintain consistent follow-up processes without manual intervention.
Klenty is significantly more versatile in outbound channel support than Apollo
While Apollo only supports email, LinkedIn, and phone steps in sequences, Klenty offers additional channels like WhatsApp and SMS. This broader channel support is particularly valuable for sales teams needing to reach prospects through multiple communication channels, especially in markets where WhatsApp is a primary business communication tool.

Advantages of Apollo

Apollo offers email warmup capabilities while Klenty does not
Apollo includes built-in email warmup services, which Klenty lacks entirely. This is crucial for teams starting new email campaigns who need to gradually build sender reputation to avoid spam filters and improve deliverability.
Apollo is significantly stronger in contact database quality than Klenty
While both products offer native contact databases, Apollo's stands out with exceptional data quality and richness. In our testing, Apollo's database proved to be class-leading compared to Klenty's more basic offering, which is particularly valuable for teams needing accurate, comprehensive prospect data for their outreach campaigns.
Apollo provides a more intuitive sequence building interface than Klenty
Apollo offers a drag-and-drop sequence builder that Klenty lacks, making it significantly easier to create and modify outreach sequences. This is particularly valuable for sales teams who frequently need to adjust their outreach workflows.

Klenty is best for

  • Businesses with diverse outreach needs across email, phone, LinkedIn, WhatsApp, and SMS
  • Who need built-in prospecting capabilities with a large contact database
  • And/or who need AI-powered call analysis for transcription, sentiment, and action items

Apollo is best for

  • Businesses with email and phone-based outreach needs who want an industry-leading contact database
  • Who need comprehensive email engagement features like A/B testing, warmup, and inbox rotation
  • And/or who need AI-powered call analysis and rich engagement analytics

Klenty is less good for

  • Businesses with simple sequence building needs who prefer drag-and-drop interfaces
  • Who need integrations with major prospecting tools like Apollo and ZoomInfo
  • And/or who need advanced email security features like domain warmup and ISO 27001 compliance

Apollo is less good for

  • Businesses with complex sales processes requiring advanced sequence branching logic
  • Who need multi-channel outreach capabilities beyond email, phone and LinkedIn
  • And/or who need advanced sales forecasting and pipeline management capabilities

Stackfix Verdict
Functionality

Functionality

8/10

<p>Klenty is very well-rounded tool. Not only does it offer support for more outbound channels than most competitors, but it also provides a strong native contact database too. Additionally, its AI features stood as some of the most thoughtful and well executed we've tested.</p>

Functionality

7/10

<p>Despite Apollo primarily being a prospecting database, we were pleasantly surprised by the quality of its sales engagement feature set. On the email front, we were pleased to find a range of rich functionality including A/B testing, email warmup and support for inbox rotation. On the phone front, the native dialer and AI conversation analysis functionalities were stand out. If we were to call out an area which was lacking it would be on the richness of the sequences builder (complex branching logic is not possible) and also any kind of sales forecasting functionality it limited.</p>
Ease of Use

Ease of Use

6/10

<p>Klenty's core prospecting and sequence building interfaces are well designed, intuitive and simple to understand. That being said, some elements of the product took some getting used to due to the sheer breadth of features on offer. On average, it would take an SMB employee less than an hour to become accustomed to the tool.</p>

Additionally, its onboarding was simple and not overwhelming. Our only complaint is that some of its sequence builder interfaces were slightly non-standard and therefore take a bit more time to get used to. On average, it would take an SMB employee less than 45 minutes to master its use.</span></p>

Customisability

Customisability

6/10

<p>Klenty offers a fairly standard set of avenues to customize your experience with the product. The most obvious comes in the form of setting up custom templates for sequences. Additionally, you can set up custom workflows and automations throughout the tool. On top of that, we appreciated that you could save search filters in its prospecting database too.</p>

Customisability

<p><span style="background-color: rgb(255, 255, 255); color: rgb(0, 0, 0);">From an engagement perspective, there are a number of customization options Apollo offers. For example, you can provide their AI with context about your business and targets which will then be used when drafting AI email sequences. Apollo's analytics dashboards are also extremely customizable and among some of the most granular we've tested.</span></p>
Ease of Setup

Ease of Setup

7/10

<p>Unlike some of its larger competitors, Klenty offers a 14 day free trial on all of its plans. Additionally, users can sign up self-serve without having to go through a sales call. Once signed up, initial setup is slick and trivial and sped up thanks to comprehensive blueprint sequence templates too.</p>

Ease of Setup

<p><span style="color: rgb(0, 0, 0); background-color: rgb(255, 255, 255);">Unlike many of similar products of this scale, Apollo offers a simple, self-serve free trial for their platform. When tested, we found the initial setup to be simple (taking &lt;10 mins), especially if you're using google workspace to power your emails. However, given then feature breadth that Apollo offers, it can take a lot of time to fully customize the experience. For example - most customers will still need to connect CRMs and customize Apollo's AI 'power-ups' to suit their needs.</span></p>

Customer Support

8/10

<p>Klenty primarily offers support via a live chat widget inside its web app. When tested, we were able to get in contact with a real agent in &lt;10 minutes. Once contacted, we generally found agents to be knowledgeable and helpful. Klenty also offers a well structured help centre too.</p>

Integratability

Integratability

5/10

<p>Klenty offers integrations with popular CRMs (Hubspot, Salesforce, Pipedrive), common email providers (Gmail, Outlook) as well as automation platforms like Zapier. We would like to have seen native integrations with more external prospecting databases such as Apollo though.</p>

Integratability

7/10

<p>Though Apollo offers a very large integrations marketplace, its clear that most integrations are geared not towards using Apollo as a sales engagement tool, but rather as a prospecting database. As such, some integrations such as document signing platforms were missing. That being said, all the core integrations including CRMs (Salesforce, HubSpot) and automation platforms (Zapier) were present.</p>
