Cold Email Tools That Won't Get You Blacklisted

The difference between inbox and spam folder. These 7 tools actually care about deliverability. Use them wrong and you'll still end up in spam though.

Instantly.ai

The Deal: Built by people who actually understand deliverability. Unlimited email accounts, smart sending limits, and warmup that works. Best bang for buck if you're doing serious volume. Interface is simple, maybe too simple for some.

Good For:

  • Teams sending 1,000+ cold emails per day
  • Agencies managing multiple clients
  • Companies paranoid about deliverability (rightfully so)
  • Teams that need unlimited sender accounts

Not Good For:

  • Teams wanting fancy multi-channel sequences (email only)
  • Companies needing deep personalization features
  • Small teams sending under 100 emails per day (overkill)

Pricing: $37/month for Growth (most popular), $97/month for Hypergrowth

Bottom Line: Best deliverability at this price. If your emails need to land in the inbox, start here.

Lemlist

The Deal: Stand out with personalized images and videos in your cold emails. Good for creative outbound teams who don't want to blend in. More features than Instantly but costs more. Multi-channel with LinkedIn integration.

Good For:

  • Teams doing creative outbound with images/video
  • Companies wanting multi-channel (email + LinkedIn + calls)
  • Outbound teams competing in crowded markets
  • Reps who want to personalize at scale without manual work

Not Good For:

  • Teams on tight budgets (gets expensive fast)
  • Companies wanting simple, no-frills email
  • High-volume agencies (Instantly is cheaper for volume)

Pricing: $59/user/month for Email Starter, $99/user/month for Sales Engagement (most need this)

Bottom Line: Pick this if you want to stand out and have budget for it. Skip if you just need to send emails.

The Deal: Unlimited inboxes and AI-powered sending optimization. Good deliverability, advanced features, steep learning curve. Built for people who want maximum control over their email infrastructure.

Good For:

  • Power users who want advanced sending controls
  • Teams managing 20+ sender accounts
  • Agencies running multiple campaigns simultaneously
  • Companies that need white-label options

Not Good For:

  • Beginners (lots of settings to configure)

Apollo.io

The Deal: Contact database + email sequencing in one tool. Good if you need both prospecting and outreach. Email features are solid but not as advanced as dedicated tools. Best value if you need the data too.

Good For:

  • Teams that need contact database + email tool
  • Companies wanting all-in-one prospecting platform
  • Outbound teams building lists and sending sequences
  • Budget-conscious teams (cheaper than buying two tools)

Not Good For:

  • Teams already using ZoomInfo or similar (redundant)
  • High-volume senders needing advanced deliverability features
  • Companies wanting best-in-class email tool (it's good, not great)

Pricing: Free tier available, $49/user/month for Basic, $79/user/month for Professional

Bottom Line: Best value if you need data + email. Get a specialized tool if email volume is high.

Outreach

The Deal: Enterprise sales engagement platform. Does everything: email, calls, social, SMS. Expensive but powerful. Integrates with everything. Requires onboarding and training. Built for teams of 50+.

Good For:

  • Enterprise sales teams (50+ reps)
  • Companies needing full sales engagement platform
  • Teams with dedicated sales ops to manage it
  • Orgs requiring enterprise security and compliance

Not Good For:

  • Small teams under 25 (way overkill)
  • Companies on startup budgets
  • Teams wanting quick setup (needs implementation)

Pricing: Custom pricing, expect $100-150+/user/month depending on features

Bottom Line: Enterprise standard. Don't buy this unless you're 50+ reps and have sales ops.

SalesLoft

The Deal: Outreach's main competitor. Similar feature set, some say better UI. Also expensive, also enterprise-focused. Slightly better for relationship-based selling vs transactional outbound.

Good For:

  • Mid-market to enterprise teams (30+ reps)
  • Companies doing consultative B2B sales
  • Teams wanting better analytics and reporting
  • Orgs choosing between Outreach and SalesLoft (test both)

Not Good For:

  • Small teams and startups
  • Transactional, high-velocity sales
  • Companies wanting simple email tool

Pricing: Custom pricing, similar to Outreach at $100-150+/user/month

Bottom Line: Outreach alternative. Slightly better for relationship sales. Still expensive.

Reply.io

The Deal: Middle ground between cheap tools and enterprise platforms. Multi-channel sequences, decent deliverability, reasonable price. Good for teams outgrowing Instantly but not ready for Outreach.

Good For:

  • Growing teams (10-50 reps)
  • Companies wanting multi-channel without enterprise cost
  • Teams needing email + LinkedIn + calls in one tool
  • Outbound teams ready to scale past basic tools

Not Good For:

  • Solo founders or tiny teams (too expensive)
  • Enterprise teams needing advanced features
  • Teams just wanting simple email (use Instantly)

Pricing: $60/user/month for Starter, $90/user/month for Professional

Bottom Line: Solid middle-tier option. Good for growing teams between Instantly and Outreach.
