It's a split decision.
Choose Apollo for prospecting, B2B contact data, outreach and dialing in one system. Its Basic plan starts at $49 per seat monthly with annual billing ($65 monthly), but includes credit limits. Choose Mailtrack for Gmail open and click tracking, starting at $6.99 per user monthly. Its cheaper plans cap sending at 100 emails and link tracking at 10 emails. These tools overlap less than their names suggest: pick by workflow, not price alone.

02Pricing compared
Mailtrack is cheaper: its listed MAILTRACK plan costs $6.99 per user per month, while MAILSUITE is $19.99. The free plan includes unlimited tracked emails, but caps sending at 100 emails and link tracking at 10 emails. The pricing page does not list annual billing or a trial.
Apollo’s Basic plan is $49 per seat per month with annual billing, paid upfront, or $65 month to month. Basic includes 2,500 monthly credits, five automated workflows and a 250-send daily limit per user. Apollo also has a free plan and a 14-day trial. Its Organization plan starts at $119 per seat per month annually, with a three-seat minimum. Compare the cost of the workflow you need: Apollo sells prospecting capacity, while Mailtrack sells Gmail tracking and related tools.
03Features and depth
Apollo covers more of the sales workflow. Its homepage lists access to 240M+ contacts and 30M+ accounts, plus prospecting, outreach and dialing in one workspace. It also offers buying signals, waterfall enrichment, and AI agents for account research, list building, outreach, follow-up and meeting booking. Apollo Anywhere connects it with tools including CRM systems, ChatGPT, Claude and Gmail. Check the credit allowance against your expected prospecting volume before switching; credits are limited by plan.
Mailtrack focuses on Gmail. It tracks opens and link clicks, keeps activity history, and sends real-time alerts. Its other tools include campaigns, mail merge using Google Sheets data, signature requests, document analytics and follow-up reminders. The feature description says campaigns can send up to 10,000 emails at once, but the listed plans also have sending limits: 100 emails on FREE and MAILTRACK, or 60,000 per month on MAILSUITE. Check the plan details against your intended use.
04Ease of use and learning curve
Mailtrack is the narrower choice: its tracking and productivity tools work from Gmail. If your need is to see opens and clicks or schedule follow-ups, there is less scope to evaluate than with a full prospecting system. Its free plan’s first-open-only history and limited link tracking may still mean checking which tier fits.
Apollo brings prospecting, outreach, dialing, data and AI agents into one system, while also connecting to tools teams already use. That wider scope can mean more plan limits and workflows to understand, especially credits, daily sends and record-selection caps. Choose it when consolidating those sales tasks matters; choose Mailtrack when Gmail tracking is the actual gap.
Questions people ask
Can Mailtrack replace Apollo?
Not for the full workflow described in these product details. Mailtrack focuses on Gmail tracking, campaigns and document tools. Apollo includes B2B contact and company data, prospecting, outreach, dialing and AI agents. If you only need email tracking, Apollo may be more scope than you need.
Which is cheaper for a small team?
Mailtrack starts at $6.99 per user per month, and its free plan may cover basic tracking. Apollo Basic starts at $49 per seat per month with annual billing, or $65 month to month. Compare limits too: Apollo Basic includes credits, while Mailtrack’s lower paid plan caps sending at 100 emails.
Does Mailtrack have unlimited email sending?
Not on every listed plan. The FREE and MAILTRACK plans show a 100-email sending limit; MAILSUITE lists 60,000 emails per month. The feature description also mentions campaigns of up to 10,000 emails at once, so confirm the relevant plan’s limits before relying on that capacity.
What should we check before switching to Apollo?
Check whether the plan’s credits, email-send limits and record-selection limit fit your volume. Basic lists 2,500 monthly credits, 250 daily sends per user and a 1,000-record selection limit. Also confirm whether annual billing, paid upfront, works for your budget; the monthly price is higher.
