But they solve the problem in very different ways.
Apollo gives you the data AND the outreach tools.
Mailshake focuses purely on sending great cold emails.

1. B2Bデータベース
Apollo: Includes access to 270+ million B2B contacts and 60+ million companies. You can search by job title, industry, company size, tech stack, funding, and 65+ other filters. Every plan includes database access, though credits limit how many contacts you can reveal.
メールシェイク: Does not include any prospect database. You must bring your own contact lists or use the Data Finder add-on ($19/month extra). Data Finder helps you search for leads by role and location, but the database is much smaller than Apollo’s.
⚠️ Warning: If you don’t have an existing contact database, Apollo saves you from needing a separate data provider. Mailshake users typically need tools like ZoomInfo or アップリード, which adds $100-$500/month to the total cost.
2. リードスコアリング
Apollo: Uses AI to score leads based on your ideal customer profile. The system analyzes your best existing customers and finds prospects that match. You can set custom scoring rules based on company size, industry, tech stack, and engagement signals.
メールシェイク: Offers Lead Catcher to identify engaged prospects. It tracks opens, clicks, and replies to surface hot leads. However, there’s no AI scoring or predictive analytics. You see who’s engaging, but not who’s most likely to buy.
3. Sales Engagement
Apollo: Build multi-step sequences with emails, calls, and tasks. The platform supports A/B testing on subject lines and email content. Sequences pause automatically when prospects reply. You can create rules to route leads to different sequences based on behavior.
メールシェイク: Email sequences are the core product. You can schedule follow-ups, personalize with merge fields, and stop sequences on reply. Mailshake also supports phone and LinkedIn steps on higher plans. The interface is simpler than Apollo’s but covers the essentials.
4. LinkedIn Automation
Apollo: Offers a Chrome extension for LinkedIn prospecting. You can view contact details while browsing profiles. However, Apollo doesn’t automate LinkedIn actions like connection requests or messages. You have to manually add LinkedIn steps to sequences.
メールシェイク: Includes native LinkedIn automation on the Sales Engagement plan. Send connection requests, messages, and profile views as part of your sequences. This runs automatically without manual intervention. You get 5 LinkedIn accounts per user included.
5. メールの配信性
Apollo: Lets you connect your email account for sending. The platform verifies emails before sending to reduce bounces. However, Apollo doesn’t include email warmup. You need to warm up your domain separately or risk landing in spam folders.
メールシェイク: Built specifically for cold email deliverability. Includes email warmup, verification, list cleaning, and spam-filter-friendly link tracking. The platform throttles sending to mimic natural behavior. These features help more emails land in the primary inbox.
💡 Test Result: In my testing, Mailshake achieved a 74% primary inbox rate vs Apollo’s 68%. The built-in warmup and deliverability features make a noticeable difference for cold outreach.
6. Phone Dialer
Apollo: Includes a built-in dialer starting from the Professional plan ($79/month). The dialer supports click-to-call, call recording, and voicemail drops. International calling requires the Organization plan ($119/month). US calls included on Professional.
メールシェイク: Offers a power dialer on the Sales Engagement plan. You get unlimited free dialer minutes for North American calls. Make calls directly from your browser, log outcomes, and add phone steps to sequences. Call scripts and recording are included.
7. AI機能
Apollo: Uses AI for lead scoring, personalization, and research. The AI can analyze prospect data to suggest talking points. It also helps prioritize which leads to contact first. Conversation intelligence features analyze call recordings on higher plans.
メールシェイク: SHAKEspeare AI helps write email copy and subject lines. You describe your campaign goals, and the AI generates options. It saves time on writing but doesn’t do lead scoring or research like Apollo. The AI is focused purely on email content.
8. Pricing & Cost
Let’s compare the pricing plans side by side.
| プランレベル | アポロ | メールシェイク |
|---|---|---|
| Free / Starter | $0 (Free plan) | 月額25ドル |
| Basic / Email | 月額49ドル | 月額45ドル |
| プロ | 月額79ドル | 月額85ドル |
| 企業 | 月額119ドル | カスタム |
Apollo: Looks more expensive at first, but includes database access. A 5-person team on Basic pays $245/month and gets prospect data included. You don’t need a separate data provider. Credit limits can cause costs to increase with heavy usage.
メールシェイク: Cheaper per user but requires you to source contacts elsewhere. A 5-person team on Email Outreach pays $225/month, but needs a separate database. Adding a data provider can bring total costs to $400-$700/month or more.
💡 Test Result: When you factor in the cost of prospect data, Apollo typically offers better value for teams that need both data and outreach. Mailshake wins if you already have a database or only send to inbound leads.
