Apollo.io offers B2B contact management and Email LinkedIn Outreach Automation. Its Database contains over 275 million contacts and 73 million companies as of 2024. The main features of Apollo include the following: Filtering by job title, company size, region, industry, Exporting targeted lists, Scheduling and Automating Sequences.
Many people in the US and Europe are using Apollo regularly. As an example, SDR Teams regularly use the Apollo platform to have quick access to contacts and leads. Apollo has subscriptions starting at $49 for a basic package up to $149 per month for their Professional Package. Where Apollo stands apart from LinkedIn Sales Navigator is Apollo provides direct emails & phone numbers rather than just profiles, without the need to spend time searching for them manually, unlike Web Scrapers.
Database Quality Does Not Mean Quality of Results. Apollo provides email lists for leads, but these lists do not indicate the level of interest by the lead on making a purchase. Bridge Group (2024) states, a typical SDR spends approximately 70% of their time manually qualifying a lead before demo (a product demonstration) and only 8 to 12 out of approximately 50 to 80 contacts will actually make it to a demo. Net-net, approximately 85% of an SDR's efforts are wasted.
Issues With Data Accuracy. A study conducted by ZoomInfo in 2024 has shown that the accuracy of email list entries within an aggregated database is between 70-75%, while phone number accuracy is only about 40-50% and that every 4th email entry is outdated. Additionally, the bounce rate for emails can average between 20-30%, which can affect an organization or individual's domain rating. Apollo does not provide up-to-date information about previous investments, executive changes, or new hires. This is important to know when conducting sales.
Limited automation: The use of email templates is primitive. Although there was an introduction of AI personalization in 2024, the AI personalization method will likely not take into consideration other things that are special about the company and its specific industry, so efficiency will still be low. The average open rate of B2B cold emailing is approximately 21% and the reply rate is only 0.5% - 1% according to Gartner's 2024 statistics.
Increasing costs: Apollo has increased its monthly subscription from $39 to $49 for its basic plan, and $199 for Full Access. An SDR team of 5 SDRs will cost over $750-$1,000/month without considering the cost of CRM and analytics tools.
Additional reasons to switch:
The purpose should be to cover the entire sales cycle of the business while having the least amount of manual work. Below are functions that should be looked for when selecting alternative SDR Tools:
Total Cost of Ownership along with Price/Pricing options. Consider pricing based on export credit amounts or other means of payment such as pay per use or free trials. Enterprise (large team) contracts. User reviews and responsiveness to negative feedback via online platforms (Reddit/G2/Capterra).
CRM systems, Email providers, Calendar and Messenger (Slack, Telegram, WhatsApp) are key integrations. Uptime should be 99.9%, API access, and GDPR compliant are essentials.

Apollo is simply another standard "database + basic automation" tool. It has limited capabilities compared to their extensive range of advanced features, such as deep real-time triggers and complete semantic AI personalization.
Modern platforms will typically allow for integration with most of the leading CRMs, email services and messenger clients, but always review for two-way synchronization or whether they provide APIs and webhooks for building custom configurations.
B2B Sales will require full automation (all aspects—from lead discovery through to instant personalized contact) by the time we reach 2026. As such, Apollo's unique benefit over traditional CRM systems is that it is easy to use for quickly collecting contact details. However, the range of its features is often not sufficient in relation to highly competitive and dynamic industries.
Therefore, we recommend using:
ASCN.AI is unique in that it reacts significantly faster (in less than 40 seconds) compared to the competition, provides no-code automation and uses advanced artificial intelligence for deep personalization based on on-chain data. As a result, ASCN.AI can vastly improve the speed of lead conversion and reduce the costs of SDR roles (Sales Development Representatives) by over five times.
