Speechify is absolutely brilliant. Growing up with dyslexia this would have made a big difference. I’m so glad to have it today.

Mailbutler reviews

I downloaded this software after hearing a coworker rave about its features, and it hasn't disappointed. Seamless installation. The tracking info, which includes when the email was opened, is such a handy feature. The Mailbutler email signature designs are sleek. The undo send is a godsend and is easier to use than Gmail's version. Highly recommend this software.

I love the send later option and that I can create tasks out of emails that are created directly in trello. It works seamlessly.

I use Apple Mail because I cannot stand Outlook. I needed two things. First, I needed to have read receipts to see who has opened my emails. Second, I needed to bcc Hubspot so that I can track all my correspondence in there. Mailbutler allows me to do both perfectly. Plus, their customer support is very quick to respond.

Proofy reviews

So easy to use, everyone on my team has been using it for a few weeks and I literally had nothing to explain beforehand. + they have free checks that you can do as a free trial so you make sure that it is the tool you wanted/needed

- Luana B. project lead

Even organically procured lists have several bounceable emails, Proofy helped us and our client's clean email lists for a fraction of most of their competitor's rates.


what I like about this app is its interface which is easy to understand. The cool thing is that the results of the verification usually return 3 categories, this isn't provided by the other app.

Pros & cons


The functionality is outstanding
It brings all the features that should have been standard in Apple Mail
These features ensure that I can focus on my business and not worrying about forgetting email messages, errors in email messages, and more
All-in-all, I would highly recommend MailButler to all night-owl entrepreneurs like myself
It will save so much time and brain space to let MailButler do the heavy lifting
I don't want to encourage clients to email me at all hours expecting a response, so the ability to snooze/schedule emails to appear and send during my business hours is a life-saver."

Every time the software is updated you need to quit and relaunch Mail in orders for the updates to take effects
Just a little small annoyance, though
The iOS application is, in my opinion, almost un-useable, given that it has almost no integrations with Apple Mail that I use as my main email software
This is no longer possible with the new formula
Unless you spend a boat-load, they limit which features you can use
Even for the ones you can use, they limit all your available "Actions" so you can only use them a certain number of times (dumb)."


It perfectly validates the entire email list no matter how big the email list is
The things that I liked the most is its easiness to use
You can verify the email addresses and clean your email lists effortlessly
Amazing experience using Proofy email verification service
Very soomth, fast and reliable software
It's really useful to get verified emails at good accuracy."

When emails are undeliverable we can not send it again and stop delivery
There is only drawback is it has no Wordpress plugin available, maybe it will come near future
Ve tried many services, most of which have done half the job, while some have been too costly for our business model before we find
With Proofy I can finally verify emails and block spammers and people intentionally lowering my sendgrid reputation."
