We use replyapp for connecting our products with relevant businesses who we think we can help.
In general it's a nice polished app, that's fairly easy to use.
The Zapier integration is handy, albeit missing a couple options that similar tools have developed.
The composing emails section is nicely done. It feels like you're writing an actual email which helps.
The campaign stats are useful, as are the a/b tests, although these are thrown by non-matched auto-replies (unless you do a fairly complex set of actions). The campaign on/off sliders and colorful stats charts make what can be quite a grey subject into quite a nice experience.
One major plus is the ability to send from multiple email accounts, and the easy connection with email accounts that send via one service (like mailgun) and receive via another (like gsuite email).
Another major plus is the responsive support crew. Reply uses intercom so you can see who's available and when you're likely to get a reply. The clarity in that is excellent.
There's a few niggles which combine to be distracting.
Reply doesn't track replies from forwarded emails, or rather, it half-tracks them. The reply shows up in the original contact thread, but not in the campaign inbox or stats. Workable by cross-referencing the inbox it's connected to, to catch the otherwise missed replies.
Dealing with un-matched auto-replies is a bit more effort than it should be, as is blacklisting domains where someone replies negatively. (It's about a 4-step process on 2 tabs). Basically your campaign stats will be incorrect without some guesswork and clicks.
The design in general is excellent, with 2 minor exceptions. The replied-email thread design is a bit too minimal, and it's also hard to blacklist a contact from in the same section.
There's some weirdness that takes a little muscle memory to resolve, like searching for a contact, performing an action, then searching again - won't work without a page refresh midway.
The way that emails are categorized is a bit too hidden; if this was more customizable with text to search for and match, and the actions to take, it'd be much clearer.
When importing contacts via csv, this is less easy than competing tools. You need to match columns to reply fields for every import, even if you're using the same format, and even for 'obvious' ones (Eg. column labeled 'email'). This makes it more effort than it should be to import your own contacts. There's some more design weirdness here, you can only import contacts via csv to the 'god view', but not into specific campaign contacts.
The a/b testing is nice, it could be improved with auto-choosing the winner after a set number of wins.
The pages are a bit slow to load, you're quite often watching the spinning wheel. As it's missing a few chances for 1-click actions (e.g. blacklisting from inside the inbox message), you do need to see the spinning wheel quite a bit.
These are all pretty minor though - in general it's an excellent product.
We're trying to let businesses, that haven't heard from us, find out about our work and how we can help.
Reply does make this easier, and really helps get into a conversation with those potential customers.
