❓ WHAT IS MERGO?
With Gmail™ you can manually send hundreds of emails to different recipients. 
If you need to send a similar email to many recipients, Mergo can automate that task. 
You write your message, as usual, in a Gmail™ draft, you provide the list of recipients and Mergo sends your message to all of them.

————————————————————————————————
💰 QUOTA AND PRICING: 
➤ Freemium: first campaign 100% free, then free for up to 30 emails / campaign.
➤ Plans start at $1.5 / month. 
➤ Monthly, yearly & lifetime plans available.
➤ Team plans available for Google Workspace domains.

🪄 USE AI TO WRITE HIGH-CONVERTING EMAILS IN MINUTES
Mergo uses ChatGPT to check the subject of your email campaign and tells you if it should be improved to boost your chances of getting your emails opened.
It automatically suggests 3 new subjects that could perform better.
After sending your email campaign, Mergo automatically suggests content for follow-up emails to boost engagement / response rate.

Need additional help to write the content of your campaign?
You can use ChatGPT or Copy.ai to create effective marketing messages that grab your audience's attention and drive them to take action.

Those tools can help with grammar and spelling, so your emails will be error-free and professional. They can also write entire emails based on a few keywords.
Simply open ChatGPT, ask it to write your email and copy paste the content into a Gmail draft. You can even indicate that you are running a mail merge campaign and give it merge tags to include in the draft.

🔒SECURITY
Most of your data never leaves your Google account (your list of recipients stay in your spreadsheets, your email content stays in Gmail™). 
Please read the Data Access & Data Storage sections of our Privacy Policy to learn more.
https://www.mergo.app/privacy-policy
We also go through a security assessment once a year (by firms like Bishopfox and NCC Group). 
This assessment helps keep Google users’ data safe by verifying that Mergo demonstrates capability in handling data securely and deleting user data upon user request.

🤔 Why use Mergo instead of its competitors?
Many apps are available on the Google Workspace Marketplace to send email campaigns. 
Mergo is the first one entirely built on the new generation of Google add-ons: all the code running in your web browser is served and secured by Google (no custom HTML or Javascript with potential security threat, no hack of the Gmail™ user interface like Gmass does).
Some, like Mailmeteor, are not as integrated as Mergo with Gmail™. They can’t use Gmail™ drafts, can’t track responses and can’t perform follow-ups in the same email threads.

————————————————————————————————

It stopped working, "There was an error! The API developer key is invalid." I followed all the different options in their troubleshooting, and more. Nothing, same error. Requested help, two days later, still waiting for their email. Now I want my money back.

Disappointed, i paid for a lifetime licence whitch worked ok for a while, but now it doesn't recognise my subscription and I cant get a response from emailing the company. Looking at other reviews it looks like I'm not the only one who has paid for a subscription only for that subscription not to work

It's unfortunate my review will likely be drowned out by all the fake reviews here. This addon is pretty useful overall. It's handy if you don't need to send any more than ~1500 emails per day, and want to keep track of opens, bounces, unsubs, etc.. There's a significant flaw with resetting people who've unsubscribed. After removing someone from the unsubscribed list, if you open the tracking report for that sheet the person will be added back to the unsubscribed list. If you don't have many sheets to search through, you can manually find the contact and edit/remove their entry. But if you have many sheets it would be very tedious, if not impossible to find and edit them. The unsubscribe button is also super easy to misclick because it looks like "small linked text" surrounded by a bunch of whitespace, but it's actually a large invisible bar that spans the full width of the page. Deliverability: When I first tried this app some years ago I had open rates of around 70%. With other popular email clients like Convertkit, Mailerlite, Getresponse, SendPulse, I get 50-70% open rates. I'm sending the same emails to the same recipients. More recently my Mergo open rates dropped to as low as 20%, and support seemed to have no clue. When I asked for a refund (I just bought it 2 weeks ago and had to drop my sending to 50/day due to the poor open rates) due to the poor open rates and unsubscribe glitch, they've ignored me.
