"Does exactly what I needed"

4/5

What do you like best about Mailbutler?

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. Review collected by and hosted on G2.com.

What do you dislike about Mailbutler?

There's a little bit of bloat on the feature side but I don't use that. I'm sure there are people that use it for contact management but it's not something I needed. Review collected by and hosted on G2.com.

"Mailbutler is SO HELPFUL."

5/5

What do you like best about Mailbutler?

I really love that if I mention that I am going to attach a document, I receive a warning if I try to send the email without attaching anything. I also appreciate that I can respond to emails and set them to send at a later time, for instances when I am trying to catch up, without letting anyone know I am working at the time. It's also very helpful to see if the person you sent the email to ever received it and/or opened it, it makes follow ups much simpler. Review collected by and hosted on G2.com.

What do you dislike about Mailbutler?

Sometimes it slows down my email, or my email glitches when trying to send an email. It is very seldom that this happens, so I still think it's worth it! The positives outweigh those negatives. Review collected by and hosted on G2.com.

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

Tracking emails and responses is much easier. Knowing whether or not recipients are receiving my emails is also helpful. If I notice someone received the email, but never opened it, it's safe to assume it went to spam - which allows me to follow up with some knowledge of why I haven't heard back. Review collected by and hosted on G2.com.

"This is excellent add-on software to consumer grade mail options"

5/5

What do you like best about Mailbutler?

MailButler is excellent add-on software for our email client. I use Apple Mail and it is the only plug-in for the app that I have consistently used for the last three years and I cannot imagine using Mail without it. As a very small business owner with very big needs for managing and monitoring email, MailButler is a gamechanger. It turns average built-in software into a rival for a full Microsoft Exchange deployment for an individual user, at least in terms of features. Review collected by and hosted on G2.com.

What do you dislike about Mailbutler?

Every so often the developers will change something and I have to root around to find it. Almost all changes tend to be for the better though and the hunt is worth it. Review collected by and hosted on G2.com.

Hi, thank you so much for such amazing feedback! We're truly grateful for your words, it helps us stay motivated and always do our best to serve our awesome customers such as you. We appreciate the 5-star rating!

"Cool Pro Signatures"

5/5

What do you like best about Mailbutler?

Signatures are eye popping and professionally done. Love it that signatures have the option to attach you company logo. Great branding ability. The signatures allow you to include links to social media sites of yours with the logo of the media site, rather than an ugly link. I can reminders to follow up on emails. Email scheduling is super useful. Review collected by and hosted on G2.com.

What do you dislike about Mailbutler?

Some recipients' servers strip tracking ability. Also, some servers tend to prevent accepting email, because of the large number of recipients in the email. The workaround is to group the emails but then you will lose the ability to have everyone's replies being visible to all recipients. Review collected by and hosted on G2.com.

Recommendations to others considering Mailbutler:

If you are an Apple Mail user who wants to use emails with powerful branding capabilities and to ensure delivery and opens and clicks, Mailbutler gives you an affordable way to do it. It is also so simple to use. Just select the signature template of your choice, edit and save. Then on Apple Mail, choose the default signature for each email account. Review collected by and hosted on G2.com.

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

Previously, I couldn't track who opened my emails and clicked on links and how often they opened as well the time. Now all of these are visible. Now I also have real-time notifications of when my emails are opened and by whom. I can also get detailed information of each person who opened and clicked on the links in the email. So, I can now get clarity on who doesn't open my emails and call them if needed. Review collected by and hosted on G2.com.

Hi James,

Thank you for the positive review! We're thrilled that you find our signatures eye-catching and professional. We're glad you appreciate the reminder and email scheduling functionalities. Thank you for choosing Mailbutler!

"Mailbutler Professional - Better than Apple Mail alone, but..."

3.5/5

What do you like best about Mailbutler?

I really like the send later and snooze functions as well as knowing when an email I send has been opened, but over the years, Mailbutler tends to slow down and sometimes even crash AppleMail...it seems to me that fully building the Dashboard and other settings into the Mail plugin itself, is the source of the problems...it worked better when all of the Administrative functions were on their website at bowtie.mailbutler.io. Dont' get me wrong, Mailbutler gives AppleMail many of the features that should have natively, but they also have too many pricing tiers. Also, you cannot create a custom signature without moving up from Professional to Professional Plus...custom signatures should be a basic feature for all tiers of subscriber...

"An Amazing Add-on for Apple Mail that enhances correspondence with clients and suppliers"

4.5/5

What do you like best about Mailbutler?

I really like the ability to schedule e-mails to be sent at various times during the day. Particularly useful is the tracking of when the e-mail is opened and when any links in the e-mail are clicked on. The ability to add a follow-up task is particularly useful as it prevents losing track of important conversations. Review collected by and hosted on G2.com.

What do you dislike about Mailbutler?

1) Would like to be able to change subject lines of incoming e-mail to something to make them more pertinent for filing, particularly when the content of the e-mail has evolved or changed. This can be done in Office 365 but not in Apple Mail, without exporting, editing and importing the e-mail, which then changes the timestamp and other key information of the e-mail. Not sure if Mailbutler can create a work-around or do anything with this request. 2) Would like to have better tracking of when multiple recipients open e-mails, but this may be a higher paid subscription than I can currently afford. Review collected by and hosted on G2.com.

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

Problems & Benefits to using Mailbutler: 1) Ability to work on e-mails later in the evening and scheduling to send early the next morning while I am busy with other work issues 2) Tracking when recipient opens the e-mail allows me to be prepared for phone calls from recipient or allows me to follow-up with the recipient 3) Ability to add notes to e-mails, particularly when I have a conversation with the recipient. All the related info is in one spot. 4) Ability to schedule follow-up tasks to ensure that important conversations do not get lost Review collected by and hosted on G2.com.

"Minimalist UI with clean, intuitive controls"

5/5

What do you like best about Mailbutler?

I needed a clean, simple, intuitive add-on to Apple Mail. Mailbutler fits right in and is seamless. I can't say enough good things about the UI/UX. The icons are intuitive, the UI is minimalist and easy to navigate and it doesn't make me feel like I have an add-on installed. It feels just like the Apple Mail I know and love. I use about six email accounts all within Apple Mail and Mailbutler handles it all beautifully. I'm looking forward to trying signatures next and exploring the tracking system. Mailbutler is quickly becoming a "must-have" for our company rather than a "nice-to-have." Review collected by and hosted on G2.com.

What do you dislike about Mailbutler?

There are almost too many features - it's taking me a bit to learn all of the tools, but luckily their onboarding emails drip helpful tips. I have to admit that it is a touch overwhelming with all of the features. I'd almost like to install each feature one at a time as I need them. Some of the follow-up features took me by surprise. It only took me a minute to hide them, but was a little jarring for the first few hours of using the tool. I'm sure it's awesome once you get the hang of all of the tools, but just didn't have time to learn that. Review collected by and hosted on G2.com.

Recommendations to others considering Mailbutler:

Test out options, but if you're using Apple Mail, the available apps are pretty limited. I'll be honest that I looked at several add-ons and they looked shady, and I wasn't comfortable installing them. Don't be afraid of the cost of Mailbutler. The free version gives me tons of functionality and features. I will upgrade to paid to get all of the bells and whistles because it's a pleasure to use. If you add up the productivity savings, it's worth every penny. Review collected by and hosted on G2.com.

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

I started by looking for an Apple Mail add-on to flag me if I sent an email without an attachment. Mailbutler had great reviews and other great productivity features (like email tracking), so I gave it a try. My productivity has improved, and it has already caught several times where I've wanted to send an attachment but forgot to attach the file. So it's making me look more professional, that's for sure.

"Mailbutler for OSX is life changing"

5/5

What do you like best about Mailbutler?

Not sure why Mail wouldn't by now include what Mailbutler brings to the table, but thank God for these features. I dreamed of a way on Mac to delay send, schedule send, set follow ups, confirm receipt and searched years ago for such a tool. Bam! Finally found it! The features' value is obvious. The support is great, tingly, personal and accountable to themselves and myself. They constantly innovate. I do wish the price was less but for how much I use email in business I would pay that as an app much like 365 or other. I haven't used the mobile version much yet but have gotten others in my org to use it and they love it. Review collected by and hosted on G2.com.

What do you dislike about Mailbutler?

Sometimes in the past there was some compatibility problem easily solved by enabling a setting which was often corrected in next version. Probably related to OS X changes or conditions at my mail providers. Review collected by and hosted on G2.com.
