Campaign Creation: Engage Leads Across Multiple Channels

Reply.io edges out with its versatile communication channels, including email, LinkedIn, SMS, and WhatsApp, and the ability to create sequences using templates, from scratch, or with AI assistance.

Reply.io's interface for creating multi-channel sequences

Its conditional variables feature allows for smarter, more targeted outreach. lemlist's visual sandbox for building sequences is excellent for complex workflows, but Reply.io's additional channels and AI capabilities may provide a more rounded tool for sales teams looking to engage leads across various platforms.

While both platforms offer robust campaign creation tools, those needing a broader range of communication channels and sequence personalization will find Reply.io's offerings more comprehensive. Meanwhile, you can enrich your leads with Bardeen, which uses AI to gather fresh and accurate information, personalizing your outreach to improve engagement.


Visual sandbox setup for complex email and social sequences.

When we used lemlist's Sequences feature, we noticed it was particularly effective for creating and managing multi-step campaigns. The use of a sandbox for setting up sequences means you can visually map out your campaign, adding conditions and actions to better engage with your leads through both email and LinkedIn.

  • Visual Campaign Mapping: Create your campaign flow in a sandbox environment, which makes complex sequences more manageable.
  • Email and LinkedIn Integration: Reach out to leads using both emails and LinkedIn messages, allowing for diverse touchpoints.
  • Conditional Branching: Add conditions that determine the next steps in your sequence, such as sending a follow-up email if a lead clicks a link.
  • Automated and Manual Steps: Combine automated emails with manual tasks, such as calls, to personalize your outreach.
  • Campaign Duplication: Save time by duplicating successful campaigns and reusing them for different leads or purposes.

Deliverability - Safeguarding Your Email Reputation

Reply.io provides a basic level of deliverability support with rate limits and manual blacklist capabilities.

Reply.io's email safety features include basic rate limits and handling options for bounces

However, unlike lemlist's lemwarm, it lacks a dedicated email warming feature, which is key for spam avoidance and improving sending reputation.

For users who are serious about email deliverability, lemlist with its integrated lemwarm service is the stronger option, though it requires additional investment. In contrast, Reply.io users should consider employing an external email warming service to complement its existing features.

Pairing either service with Bardeen can enhance personalization and potentially improve open and response rates, further aiding deliverability.

Settings for email safety and rate limits in reply.io.

Reply.io's Sequences feature addresses deliverability issues with several practical tools. It supports basic rate limits on emails and allows the use of multiple inboxes, but it's important to note that a single campaign can't be sent from multiple inboxes simultaneously. While reply.io does provide some in-built tools to help with deliverability, we recommend using an additional email warming service to enhance your results.

  • Email Warming: Not directly offered; external service recommended.
  • Spam Avoidance: Basic settings to delay emails and manage auto-replies and bounces.

  • Multiple Mailboxes: Supports use but not for a single campaign simultaneously.
