Looking for the best Reply.io alternative?

If you're into outbound sales and marketing, you've probably heard of Reply.io.

While it's a good tool for one-time outbound outreach campaigns, it has some limitations in its capabilities.

In this article, we have rounded up the seven best Reply.io alternatives that you should consider when looking for a more powerful and comprehensive outbound marketing tool.

Before we go into those, let's quickly discuss what Reply.io is and its main limitations.

What Is Reply.io And What Are Its Main Limitations?

Reply.io is a sales engagement platform that enables businesses to automate their sales outreach and follow-ups. 

Using it, you can create and launch email campaigns, track email performance, and follow up on prospects with personalized emails.

However, Reply.io has some limitations in its capabilities, which are:

1. Doesn't support cold outreach scaling. Reply.io users in G2 say it lacks scalability, notably because it lacks inbox rotation. Inbox rotation is essential for scaling cold outreach as it spreads email volumes evenly over multiple inboxes, preventing them from landing in the spam folder.

  • "Even though we used Reply.io's internal deliverability tools for cold outreach, we would still end up getting email sequences marked as warning or fully suspended"

  • "Not good for anyone who wants powerful sending features and requires a consistent, reliable solution."

  • "It lacks general features for power users."

2. Using Reply.io can be clunky for users. The way in which replies were managed, integrations, available Chrome extension, and creating email sequences were reported as unintuitive by Reply.io customers.

  • "There are massive functional differences between the web log in and the Chrome extension. Views are different, and you have to use the extension on top of the web log in for some functions and views to work."

  • "It is incredibly confusing to integrate with Hubspot, and I'm very technical. I needed to write into support, and it still barely worked."

3. Expensive to use, and most features only available with premium plans. For example, if you want advanced reporting features or more than one inbox to send emails, you must opt for Reply.io's Professional plan, which costs $90 monthly.

  • "Pricing is not as it seems. You are limited to only a few email accounts, with $29 added per email account per month afterward.

These are the main limitations of Reply.io. Some users on Trustpilot have also reported Reply.io having bugs in everyday use.

These may not be dealbreakers for you, especially if you want to send out basic email campaigns to your recipients.

But we've listed the seven best alternatives if you’re looking for tools that can do more with their features.

The 7 Best Reply.io Alternatives To Get Results From Email Outreach

1.QuickMail - Get better results from your cold outreach

Powerful cold email outreach solution with advanced email deliverability features

QuickMail vs. Reply.io Key Differences

  • With features like built-in inbox rotation, QuickMail is made for scaling your outreach efforts, while Reply.io works for one-off campaigns

  • QuickMail has native integration with the free email warm-up tool MailFlow, making sure that your emails land in the recipient's main inbox.

  • Get started with a free 14-day trial and send up to 3,000 emails a month at no cost, whereas Reply.io's free plan only allows you to browse the platform

  • QuickMail gives agencies one unified dashboard view of all client's inboxes

Personalize Every Email You Send

Cold email only works if you get replies to your campaigns.

QuickMail has all the tools you need to create unique and personalized emails

To start your campaigns, you will create a prospect sheet using Google Sheets or CSV, or you can import prospects to QuickMail using Drive.

The next step is to write your personalized messages. In QuickMail, you can easily add attributes to your email campaign to personalize each message for your prospects. 

Personalization is essential to succeeding with your cold emails, as it will help you increase your open and reply rates.

If you want to do multichannel outreach, you can integrate Aircall into QuickMail and make cold calls from within QuickMail.

Scale Your Cold Email Campaigns Effortlessly

One of the biggest limitations of many outbound tools is that they don't let you scale your cold outreach campaigns.

QuickMail removes this problem.

You can add multiple inboxes to one account, even with the free plan.

And if you are managing campaigns for multiple clients, you won't need to log in and out all day long. In QuickMail, you have a unified dashboard for all inboxes where you can see all necessary information, such as how the campaigns are performing.

If you want to scale the number of emails you send per day, you can quickly add a new inbox to that campaign. 

With the help of the inbox rotation feature, you can increase your email volume without causing issues with email sending limits.

If you are a team, you can also invite unlimited team members to QuickMail.

Keep Your Inbox Safe

QuickMail integrates natively with MailFlow, a free email warmup tool that ensures your email doesn't land in the spam folder.

MailFlow sends and receives emails on your account, and if an email you send to another inbox in our network lands in spam, it will be automatically removed and replied to.

This will show ESPs like Google that your emails deserve to land in your prospect's primary inbox and keep your email health score high.

Compared to Reply.io, there are no email warm-up tools available, which puts your cold emails at risk of landing in spam folders.
