👨 Marc Goldman, CEO of Send13 & Klean13

I’m super excited to bring my many years of email deliverability experience to the WordPress community so we can help more small business have their WordPress emails reach the inbox!


MailHawk is making sending email from WordPress easier and more transparent with these innovative features.


Wondering if your emails are reaching the inbox? You can see your deliverability rate right within the MailHawk dashboard on your WordPress site! Use this information to make adjustments to your emails to improve your deliverability!


MailHawk provides SPF and DKIM authentication methods. This will drastically improve your email deliverability and provide you with a greater chance of skipping the spam folder.


Stop spam from ruining your sender reputation by maintaining a blacklist of emails and domains which are causing you issues. Bounced emails can be automatically added to the blacklist so don’t have to worry about invalid email attacks.


Keep track of your emails and debug email sending failures! You can resend emails, retry failed emails and even see which emails bounced! If you ever need to prove an email was sent you can check the log for up to 14 days after the email was sent! View content, headers and even the raw MIME message if you need to.


Are you using Multisite? MailHawk can be enabled across your entire multisite so you only have to configure it once!

I purchased this product because it was recommended by the Groundhogg Co-Founder Adrian. I am using Groundhogg for my CRM. I thought this purchase would give me access to an email box for my new website. I guess it doesn’t. It only gives support for emails produced from my website.Why the 1 star? I emailed for help. I could not find any supporting documentation or videos that demonstrate MailHawks services. I even emailed their customer service for help and I got 1 response for more information and then no response. I followed up 2 days later to see what they thought and got zero response. Because of the terrible customer service, I’m now starting to question whether or not I want to use Groundhogg.

This plugin hasn’t worked well for a good three months straight. Emails stop coming in from a simple contact form made on Gravity Forms. We have reported the issue via tickets, but their response has been absolutely lousy. They temporarily fix the issue as it breaks again after just a few days. This last time, they have completely ignored us and cut off communication. We have written 4 times and have waited 7 days to hear from them, but nothing. Meanwhile we are copying and pasting emails. This has only been a constant headache, waste of time and money (you are charged monthly for this “service”).

I was looking for a more robust WP email sending service for my WordPress Multisite install. With MailHawk, I was able to launch a full premium sending service in no time. After I tested the plugin, I had my sites sending emails in no time. The issues that I encountered were answered within 24h. I could not expect more from the MailHawk support. I look forward to seeing a dashboard widget in a future release. For closing; premium sending for my WP emails, was done with setting up my DKIM and SPF, all from within my WordPress site. I installed MailHawk site based, not network activated. This gave me the option, not to include all sites in my network. Keep the good work going.
