1. 목적 및 범위
곧: Instantly is a complete sales engagement platform for cold email campaigns. It handles sending accounts, automated outreach, the campaign builder, and reply management in one product. You can run separate campaigns, mark leads by intent, and track response rates from a single dashboard.
마일도소: Maildoso is a cold email infrastructure provider, not a cold emailing tool. It provides mailboxes and sending domains but does not run outreach campaigns itself. Cold email marketers connect Maildoso to a separate platform to send emails.
2. Unlimited Email Accounts and Inbox Rotation
곧: Every plan includes unlimited email accounts for outreach. With unlimited accounts and inbox rotation, sending emails spreads across all your sending accounts within a single campaign. This protects sender reputation and lets you send thousands of emails without hitting per-account limits.
마일도소: Maildoso provides unlimited inboxes capped by plan tier. The starter package offers 32 mailboxes; the agency pack gives 400. IP rotation across multiple email accounts helps avoid spam filters during cold email outreach.
3. Email Warmup and Sender Reputation
곧: The warmup feature is built in and unlimited on every paid plan. The deliverability network includes over 1.5 million users, making it the largest peer-to-peer warmup pool. The warm up simulates human-like conversations to build sending reputation and dodge the spam folder.
마일도소: Maildoso lacks a built-in email warmup feature on standard plans. The AI-powered warmup is an extra cost ranging from $160 to $2,000 per month. Without warmup, cold emails risk hitting spam folders before building sender reputation.
⚠️ 경고: Email warmup is crucial for cold email campaigns to build a positive sending reputation. Maildoso’s missing built-in warmup is one of the biggest tradeoffs versus Instantly.
4. Lead Generation and B2B Lead Database
곧: The Instantly lead finder taps a B2B lead database of 160M+ contacts via SuperSearch. You can filter verified leads by industry, role, LinkedIn URL, and revenue. The lead lists feed directly into outreach campaigns to scale your outreach.
마일도소: Maildoso does not provide lead generation tools. You bring your own lead lists from third-party sources. The platform focuses on email infrastructure rather than finding potential clients.
5. Campaign Builder and Automated Outreach
곧: The campaign builder uses smart scheduling and conditional follow ups. Custom variables enable personalized emails at scale. You can set up automated outreach with separate campaigns for different sales strategies and book meetings around the clock.
마일도소: Maildoso has no campaign builder. You pair it with a separate cold email tool like Instantly or Smartlead to run email campaigns. This adds another subscription cost but gives more control over your stack.
6. AI Features and Personalization
곧: 그만큼 AI 비서 writes subject lines, full email content, and entire sequences. Custom variables and conditional logic create personalized emails for each recipient. AI categorizes replies by intent, which speeds up early-stage conversations and helps close deals faster.
마일도소: Maildoso offers no AI features for writing or personalization. The platform focuses purely on email infrastructure. You handle email content in your separate outreach tool.
7. 통합 받은편지함 및 답장 관리
곧: The unified inbox is called Unibox. It pulls every reply from every email account into one feed. The AI marks leads as interested, not now, or unsubscribed so you can respond to hot prospects first.
마일도소: The master inbox displays all replies from all mailboxes in one view. You can track conversation history per recipient. The master inbox lacks AI-based reply classification you get from Instantly’s Unibox.
8. Email Deliverability and Spam Filters
곧: Email deliverability comes from the 1.5M+ warmup pool plus integrated email validation. The warmup simulates email opens and reads to build sending reputation. Users have reported getting 2-5 meetings every day after setting up their first Instantly campaign.
마일도소: Maildoso uses shared IPs, which can cause inconsistent deliverability depending on other users on the same IP address. Three dedicated IPs are available as an upgrade for better deliverability. Without the built-in warmup, sender reputation builds slower.
⚠️ 경고: Cold email infrastructure providers like Maildoso depend on shared IPs by default. Three dedicated IPs cost extra and shared IPs can drag down high deliverability.
9. Domain Management and Setup
곧: Instantly connects to email accounts you already own through Google Workspace or Microsoft 365. You handle domain setup outside the tool. The platform does not bulk-provision lookalike domains for you.
마일도소: Maildoso handles domain setup and mailbox creation automatically. The small package covers one domain, the starter package covers three domains, and the agency pack covers five domains. Domain forwarding redirects lookalike domains to your main site for brand protection.
10. Integrations and API Access
곧: Standout features include 자피어 integration and native links to popular CRMs. The platform connects to your sales engagement stack through API access. According to user reviews, integrations are easier to set up than SmartReach IO’s native CRM connectors.
마일도소: Maildoso integrates with cold email and marketing tools like Instantly and Smartlead. The API access lets developers automate mailbox provisioning. Maildoso alternatives like Inframail and Mailforge offer similar integration breadth.
