"Personalized at scale"
What do you like best about Reply?

Dead simple to import prospects and set up complex and varied outbound campaigns. Emails look like they come from you directly.

What do you dislike about Reply?

No big complaints! I uploaded duplicate contacts which were a bit hard to dedupe in the product, but I was able to delete and reupload relatively easily.

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

The goal was to be able to quickly test different outbound campaigns to figure out which messaging was most impactful. With Reply, it was easy to do this in minutes.

"Amazing customer service"
What do you like best about Reply?

The customer service is absolutely amazing. Plus they have great resources on their blog to ensure you succeed. I also like that they provide in-depth stats on your campaign performance and A/B testing capabilities for the subject line and email body.

What do you dislike about Reply?

The bounce email filter could be improved. Not all email that bounces get flagged by the system.

"Email automation with a personal touch"
What do you like best about Reply?

I love the ease of use, tracking and filtering features and how it integrates with all my other apps.

What do you dislike about Reply?

Their isn't anything I really dislike. Sometimes the pages can take a while to load but apart from that it does everything I need and more.

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

Cold emailing both sides of our platform when launching in new territories. its great for getting a full picture of what is happening with our email outreach. We also use it to warm up customers who we plan to cold call. Once set up the software will save you time and allow you to send personal emails which have been tested over time.

What do you like best about Reply?

Fairly easy to use platform with a high level of customization to your email campaigns. Their custom support team is very responsive as well.

What do you dislike about Reply?

Stats can be confusing sometimes. The aggregate score of your reply rate for example, is the reply #/total # of contacts. Reply.io also doesn't really support outlook.

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

Sending tailored messages to a large list of clients.

"Good Tool for Personalized Outreach "
What do you like best about Reply?

The best thing for me and why I decided to use them is they had all of the features I need for email outreach, at the right price.

What do you dislike about Reply?

The only thing I dislike is the app can be a bit slow at certain points, but most of the time there are no issues.

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

We are able to have personalized outreach that scales. Our team is doing better with follow up and proactively contacting prospects and channel partners.

"Easy to use but supported 100% of the way"
What do you like best about Reply?

Easy to set up and get going, syncs with my major databases which makes for easy reach out and tracking both on personal level but great for business insight to. Im not the most technical so relied on support to give me a nudge and they were very responsive and extremely helpful.

What do you dislike about Reply?

There are a number of features that I may not be leveraging to their full potential. I'd love to be able to track when an email is forwarded on and to whom.

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

I can easily personalise a message and send it to a specific group of people across multiple industries at the touch of a few clicks. This is pivotal for a small yet rapidly expanding business to continue that growth in the right way and the tracking allows me to stay personal.

"Solid Email Marketing Software"
What do you like best about Reply?

Really clean interface and nice reporting. The feature to send in the recipient's time zone is particularly strong (you have to update their city/state/country). Great customer support - that's probably the biggest reason I've stayed with them.

What do you dislike about Reply?

Don't find much value in the tasks, lead finder, or phone caller. I think this is more so the job for a CRM but get that because Reply's owned the email marketing side of things, they're looking to expand in different ways. The reporting gets a bit tough - wish there was an easier export all data so that custom reporting could be done more quickly.

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

Helps set great cadences. There are other solutions like Yesware, but having a solution in the cloud helps centralize the data from the campaigns and makes it easier to control everything.

"Invaluable tool for cold emailing"
What do you like best about Reply?

It's incredibly simple and quick to set up a cold email campaign in Reply. The plain text emails from Reply resemble real, 1-to-1 emails better than any other email automation tool we've tried.

What do you dislike about Reply?

They've added a ton of extra features, which can be a bit distracting/confusing from the core product. The performance reports/data from campaigns are also not the most intuitive to use.

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

Highly-personalized cold email, at scale. Reply allows us to kickstart sales

"Easy to get started"
What do you like best about Reply?

The layout is simple, clean, easy to navigate. If you are new to email campaigns (and I was) its pretty easy to get started. If I get stuck on a step, I can chat with a product expert right from that screen. I have also found the email verification to be pretty accurate. Even though I use other sights to help gather contact information, I've learned that if Reply says its :not a valid email" its usually right! I would really like to have an integration to LinkedIn Sales Navigator to more quickly import information.

What do you dislike about Reply?

I find it confusing to know which features I should leverage inside Reply.io and which ones I should use in my CRM. For example, why would I use the "Tasks" feature in Reply vs. my CRM. What additional value does it bring me? I'm a 1 person shop so I don't have a lot of free time to investigate features. I need to get going quickly.

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

2 main benefits: making contact with new clients; quick visibility into who's really reading my mail.

"A real time saver"
What do you like best about Reply?

The tool is very intuitive and easy to use. Its easy to create a campaign and the custom variable inputs allow you to simply personalize each message. The analytics once a campaign are live are brilliant. For any sales/marketing person that uses email as part of their outreach strategy, this tool is a must have.

What do you dislike about Reply?

Have been using for 2 months and there is nothing that comes to mind.

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

Creating and managing mid-large scale email campaigns, less time spent reaching out to more people. The analytics have helped to understand how successful my campaigns actually are.

"Great platform but a lot to improve "
What do you like best about Reply?

Overall, Reply is a very good system of campaign organization. I like that I have everything to measure my results in one place. I can organize my contacts, format my campaign which will go out looking like I'm sending directly from my email, and it offers very comprehensive stats. Managing all the users and compare them as a team gives us a really good insight as well.

What do you dislike about Reply?

It took us a while to really get it ready, there's a lot of layers and settings before a message can go out. We had a few issues at the beginning of using Reply because the campaign would be sent before the set schedule. After a few attempts, the issue was solved. Customer service can be tricky, although I only have good things to say about our contact people. It makes a difference, though, to have direct chat if there's any question from our end, Reply team is always very responsive :) It's a complex system to change lists in the same campaign. Too many steps of back and forth to set a campaign. I also don't like that when I export stats, it just gives me general data of the entire campaign. I would love to have more specific data exported for reporting.

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

We can keep track of prospective clients and organize or CRM through it, which improves a lot our workflow. We can send different steps and just wait for the results after a few days, instead of always checking inaccurate stats form different systems.

"Much improved user interface"
What do you like best about Reply?

Ability to set automated campaigns to reach clients. Excellent integration with Salesforce makes it a breeze to use.

What do you dislike about Reply?

The User Interface is not the best, but they seem to have made some changes recently which improved the look. However many aspects of using it are counter-intuitive making it a little hard to get used to.

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

I've been using Reply for just under a year and it saves me a lot of time in writing follow ups. I am able to make highly personalized condensed emails which don't give the recipient any idea that the mail is automated.

Cold email sending is a time taken process and reply.io simplifies that process. All you need to set up a campaign, add contacts and steps.

"Very useful marketing too."
What do you like best about Reply?

Reply is a useful email marketing tool that allows you a build a large number of email templates using your own domain now. It is highly customisable and a scaleable. It allows you to make mass-mailing look very personal.

What do you dislike about Reply?

Some of the logic of the site is not entirely intuitive and it takes a bit of getting used to. There are a few odd quirks like features that do not work unless the page is fully expanded for example. It is definitely a website that could do with being a bit simpler. Pricing could also be a bit better.

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

Our business is an online courier platform with a business model that depends on high volumes. As such, mass marketing to businesses is a necessary part of our strategy. Reply is the best solution we have found so far.

"Great tool!"
What do you like best about Reply?

Being able to send emails on behalf of different people allows me to manage all follow ups for my sales team, so they can focus in more important tasks. Also, I like the fact that I can personalise every email, try new templates, a/b tests, etc etc.

What do you dislike about Reply?

The system for making contact lists is very basic and sometimes a bit disorganised. I also feel that having a reply-history for each contact would be very helpful.

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

I can reach out to more people with much less effort. The sales team can just wait for the answers to come, and they don't have to worry about anything else.

"Reply.io - great UI and friendly support, raw contact data and overloaded tagging"
What do you like best about Reply?

UI and features list look awesome, but some still need to be developed. Support is fast and friendly. If it weren't for the support, I would have quit the service already, so many questions appeared and were solved with the help of support agents.

What do you dislike about Reply?

Low quality of Reply contact data (ok, it is still in beta) Too many labels and tags messed me up when I wanted to exclude email from particular sequences. It might be Do not contact stage (not) Paused status (can be for some time) Blacklist (the last I tried, it helped)

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

Reply helps a lot with massive, focused email campaigns. I tried Reply data as a contact mining source. It was pretty easy to work with and seemed promising, but the bounce rate was too high, and contact relevance was pretty low. So, I'm looking for new tools for contact mining.
