"Solid Outbound Prospecting With Great Support"
What do you like best about Reply?

Reply is a full-featured platform Outbound ESP with great support.

What do you dislike about Reply?

The ramp-up time for casual users is a bit more than simple platforms. Because it has full global-level control (e.g. you can throttle email sends and delays from a sequence level) it can override individual user controls, which can be confusing for casual users, but at the same time extremely powerful if you're an admin looking to manage overall email volumes and sends.

What problems is Reply solving and how is that benefiting you?

We use it for 2 use cases: outbound prospecting as well candidate outreach.

"Makes it easy to align marketing and sales outreach"
What do you like best about Reply?

Having access to email performance and tracking analytics for the sales them and being able to share campaigns and email templates across the team. Both features have allowed us to optimize our outreach efforts and grow our pipeline.

What do you dislike about Reply?

The Salesforce integration is not fully compatible with our salesforce org and requires some workarounds and manual entry.

What problems is Reply solving and how is that benefiting you?

Outbound sales. The benefits of Reply has been being able to scale cold outreach and optimize messaging and tactics.

What do you like best about Reply?

Easy to work with, helpful bot available for questions, easy to save and search templates, able to use Reply resources to make sure email isn't lengthy. Tracking emails is also a plus.

What do you dislike about Reply?

Seems like you cant set up emails for a week in advance/more. Wish you could see a calendar worth of outbox vs a week - hard to see if scheduling as planned.

What problems is Reply solving and how is that benefiting you?

ability to do lead generation and add people into campaigns, making it personalized is helpful as well. Ability to pause and edit campaigns is helpful. Ability to track email campaigns and who has opened/hasn't.

I like that live chat, they get answers to you pretty quickly. This used to be a problem, but they've clearly solved it. The UX is great, pretty simple.

"Reply is a great functional tool, despite needing a bit of enhancement"
What do you like best about Reply?

Reply provides the appearance of intimate, personalized emails which diminishes a lot of the pain associated with cold outbound campaigns.

What do you dislike about Reply?

While this format is excellent for initiating contact, it lacks the versatility necessary for communicating specific product information. Additionally, as this format becomes more widely adopted, the intended audience becomes less receptive to the perception of intimacy.

What problems is Reply solving and how is that benefiting you?

I publish software products, and am trying to communicate knowledge of the product benefits to the intended user communities. Fleet has been helpful for initial outreach, but it has limitations when following up with groups of established contacts.

"Reply covers all our outbounding needs and offers great support"
What do you like best about Reply?

It's simple and easy to use and has the functions needed for us to execute our range of outbounding activities. The UI is intuitive, but if I ever have a question, support is there within minutes to answer me and guide me in the right direction.

What do you dislike about Reply?

I think the email validation feature can be improved - it should be possible to validate as you import and it should be easy to change Reply's validation if you believe it's wrong (happens sometimes).

What problems is Reply solving and how is that benefiting you?

We're able to very easily setup, manage and execute on our outbounding campaigns. They drive additional leads and revenue for us. Needless to say it's significantly better than doing this activity manually in gmail or outlook!

"Booking more meetings!"
What do you like best about Reply?

I love the ease of use, the flexibility with monthly pricing and the fact that I can book more meetings and put some of my prospecting on autopilot. I use this in addition to the tools in my Hubspot CRM because email sequencing is limited in HS. I also think I get better open and reply rates by using Reply.io. Until Hubspot can offer the features of Reply.io, I will absolutely rely on this to keep my prospecting game strong.

What do you dislike about Reply?

Sometimes the template editor gets laggy if I've had a template open too long. I also wish that my CRM (Hubspot) had more integrations. That's mostly on Hubspots end I'm sure, but importing/exporting lists is a little cumbersome, but the value is there so its worth it for me.

What problems is Reply solving and how is that benefiting you?

I need personalized outreach to each state in my territory and I can spin up those campaigns in less than 15 minutes if I have the templates created. I have noticed that my meetings doubled when using this along side Hubspot Sequences. It doubled my outbound efforts and syncs pretty well with HS. I use Zapier to improve connectivity and to change other contact details based off the responses I get back from prospects.

"Great tool to streamline email process"
What do you like best about Reply?

I really like the inbox grouping by reply category which works great. I also like the option to reply to the email from within Reply.io.

What do you dislike about Reply?

some parts of the user interface are a bit cumbersome to use and the website is quite slow at times. These are small issues though and do not impact the overall usability of the service.

What problems is Reply solving and how is that benefiting you?

vs using my outbound email data providers emailing platform it is vastly superior and saves me at least 1h per day as i do not need to switch between applications and the whole process is more streamlined.

"Review of Reply"
What do you like best about Reply?

I like that I can put email followups on autopilot. I manage volunteers around the globe in various timezones with a variety of concerns, so its nice to be able to ensure someone else is on top of followups, and reduces administrative burden.

What do you dislike about Reply?

I wish I could change the bottom sentence that allows people to opt-out so that it read differently than "If you don't want to hear from me anymore, let me know." It's a weird wording for our use-case, but the pros outweight the cons.

What problems is Reply solving and how is that benefiting you?

I'm able to better engage our volunteers and donors. It cuts down on my administrative time and increases engagement.

Reply.io is great for focused email drip campaigns. If you need to setup cold outbound email campaigns to a list of prospect, Reply is the tool for you. With their easy-to-use campaign templates, we can set up a 5 email drip campaign within a matter of minutes.

What do you dislike about Reply?

"First timer doing e-mail marketing"
What do you like best about Reply?

One thing I asked their Sales Manager was “how easy are the functions to new believers of e-mail cadence tools?”. He was totally correct. The user experience is super smooth.

What do you dislike about Reply?

By the functions being super easy, and smooth to use, they also become really rigid as well. It would be dope if I had more freedom with how the functions function. And by them growing quickly, the system glitches from time to time.

What do you like best about Reply?

The ability to automate email marketing is necessary for a young startup that needs to have great engagement with early customers and prospects. Not to mention how helpful it is making sure your know what it takes to have great performance.

What do you dislike about Reply?

For the price, nothing. I have used far more expensive services with more sophisticated features at previous ventures but those are priced far outside of the market for young startups and mall businesses.

"Efficient and Easy to Use"
What do you like best about Reply?

Reply has a very intuitive interface and it's easy to see the success of individual campaigns at a glance. There's a vast resource library for all questions, their support staff are helpful and friendly, and the performance of campaigns is smooth and without issue. It's a platform that is great for beginner or intermediate marketing professionals running email marketing of any size. Reliable and easy to let run without unnecessary processes to maintain.

What do you dislike about Reply?

There are a couple improvements that could be made, from our experience. The system could benefit from a way to easily search for contacts via company name, not just contact name (outside of filtering individually, which takes time.) There should also be a filter for blacklisted contacts, to download for DNC lists; archived campaigns should still retain their individual in-depth stats.

What problems is Reply solving and how is that benefiting you?

Reply is really helpful for A/B split testing, and we've been able narrow down the most efficient email copy for individual industries, sectors and functions. The reports function has been helpful for calculating performance per month, week, day - in general for all campaigns and individually.

"Easiest to Implement Outbound Automation Platform"
What do you like best about Reply?

Reply.io is an extremely straightforward and easy to use platform and manages all of your data very well. I don't have to worry about someone getting in multiple campaigns nor do I have to worry about people who are out of office or unsubscribing. From an sales ops point of view, Reply just works.

What do you dislike about Reply?

Reply.io is pretty difficult to navigate when you have many campaigns. You have to scroll through them all and sometimes it takes a very long time for the page to load everything. I've had to refresh the page multiple times to get it to open. I experiences this for two years as a Reply customer. They have an archive campaign button but then the campaign is locked and I can't go back in and look at anything, not the data, and not the email copy.
