Common Issues With Instantly

While Instantly is easy to use and helps send emails fast, many people notice the same problems frequently:

• Small contact limit on basic plans – The Growth plan only allows 1,000 uploaded contacts. This makes it hard to run big campaigns.

• Weak lead results in Super Search – The built-in Super Search often gives contacts that don’t match the right target audience.

• Important tools are only in higher plans – Features like Unibox for replies or HubSpot and Apollo integrations are locked in expensive plans.

• Simple reports with little detail – The dashboard only shows basic data like opens and replies, with no deep tracking or filters.

• Hard to use images or GIFs in emails – Adding visuals in sequences often fails or doesn’t preview properly.

Instantly works well for smaller outreach setups, but limited contacts, unclear warm-up steps, and basic analytics make it harder to scale smoothly.

How We Evaluated These Instantly Competitors

When choosing the best Instantly alternatives, we focused on the main issues people often face, low deliverability, unclear warm-up setup, limited reports, and missing integrations.

Here’s the checklist we used:

• Deliverability rate and inbox reach, to see how well each tool avoids spam and improves sender reputation.
  
  

• Ease of setup and campaign launch, so teams can start sending quickly without technical steps.
  
  

• Accuracy of lead data, including filters for industry, location, and role.
  
  

• Automation and workflow features, like auto warm-up, smart follow-ups, and scheduling.
  
  

• Integrations with CRMs, such as HubSpot, Salesforce, and Pipedrive.
  
  

• Reporting depth, to check how much detail is shown on opens, replies, and performance.
  
  

• Multi-inbox and domain handling, to test how easily tools manage large sending volumes.

By using this checklist, we picked five Instantly competitors that help outreach teams improve deliverability, scale faster, and manage campaigns more easily.
