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.

HuBuCo reviews

I researched and tested about 30 different email verification programs. I filtered the list down by accuracy, then by price. It was between HuBuCo and two others. HuBuCo was the only one who really worked with us to make sure HIPAA requirements were ensured. We use Hubuco for new customers who are sending out NPS surveys to their customers.

- Emma P. Operations Manager

We sometimes get old lists from our system people and are asked to quickly turn email campaigns around. This service is a great first cleanse.

Increased leads, bounce removing, satisfied customers

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)."


I had some list that a client needed verified and HubuCo did a great job
It helps us keep our lists clean, dramatically reduces bounce-backs, and saves time
I highly recommend it as the first step with any new list
I already tried other services, overall Hubuco is better than most
Easy activation when paying and loading database."

I'm impatient with technology in general, always finding it difficult to wait for a process to complete
In addition, there had been no double opt-in for sign-up and I could tell just from the names of some subscribers that they were spam bots
Sometimes the software can act a little strange in older browsers
Via my articles I've bring to them a lot of customers (I was in their affiliate system) and they refused to pay
That was really dissapointig (and keeps me away from HuBuCo)."
