I'm a newbie and don't understand a lot of the tech lingo. I currently have Google Workspace and my business email through them. Would I need to switch to Amazon to be able to use MailBluster?
You don’t need to switch from Google Workspace — you can keep using it for your regular email. But to use MailBluster, you do need to have an AWS (Amazon Web Services) account connected, since MailBluster uses Amazon SES to send emails. That means you'll need to create an AWS account, connect it to MailBluster, verify your sender domain, and move your AWS account out of sandbox mode. We have detailed guides and resources to help you through the setup. Here's the guide: https://app.mailbluster.com/pages/aws-setup-guide . Also, if you need extra help, you can always ping our support team, we’ll assist you as much as possible. You can also reach out to us through our support email hello@mailbluster.com
Hello, I have 5 or 5 websites I want to add ways to for people to optin to emails, how many domains can I install this on? I see there is only limits can I use this on unlimited domains as long as I stay within the limits and it will collect subscribers addresses keeping them seperate so we can run campaigns separately and not get them mixed up? Thank you very much
Yes, with MailBluster, you can use as many websites or domains as you need. There are no limits on how many subscribers you collect, how many signup forms you create, or how many domains you use to send emails.
Each website can have its own signup forms, and all subscriber data will be stored in your MailBluster brand. You can assign tags to each signup form to keep your subscribers separate by website, and later create segments based on those tags. This way, your lists stay separate and you can send targeted campaigns to the right groups without mixing anyone up. You can also send emails from multiple verified domains, so with MailBluster, managing all your email marketing in one place is easy and efficient.
Q: Does the $59 deal on app sumo send unlimited emails or 30,000 cold emails?
I am currently using Instantly AI and I am paying $97 a month and I would be interested in saving money. But can I only send 30,000 emails in total with this? Or 30,000 emails per month? What if I delete old emails and want to send new emails then could I send more than 30,000 emails with the $59 deal? Let me know as I am potentially interested but I need to be able to send more than 30,000 emails over the lifetime use of this deal.
If you purchase the Tier 1 AppSumo deal for $59, you’ll get 30,000 email credits in total. This is a lifetime limit, not per month or per year, and it never expires. You can use these credits at your own pace whether over a few months or several years and they’re yours for life.
Deleting old emails won’t increase the 30,000 limit, as the deal is based on the total number of emails sent, not stored.
Once your email credits are used up, you can continue sending emails by purchasing additional credits at a discounted rate of $0.40 per 1,000 emails (regular price is $0.60 per 1,000 emails). Plus, there is no yearly subscription fee ($60). That means with this AppSumo deal, you’ll save at least $300 over five years, and on top of that, you’ll get lifetime access to all Pro features (eg. Automation, Custom Fields, Pro Templates etc.)—no hidden fees, no recurring costs. So, if you're currently paying $97/month with Instantly AI, this AppSumo deal could be a great way to save money long-term.
Hi - You made a very smart calculation. On our tire, 59/30000 —> 1.96$ per thousand email 139/200000 —> .69$ per thousand 299/500000 —> .59$ per thousand
So, you are paying less per email as you go up.
But if you want to go on a more economic route, starting with tire 1 is a viable option, as you can always purchase extra credits.
Please feel free to let us know if you have more questions.
Q: Cold Email
Hi, Can your solution be used to send cold emails ?
Yes, you can use our solution MailBluster to send cold emails. But, I would suggest you to clean the list using a email verifier tool before sending out emails to minimize the bounce and complaint rate and to keep your Amazon SES sending reputation high. MailBluster does not block accounts for cold emailing, but Amazon SES has its own rules and restrictions. As long as you comply with Amazon SES’s usage policies and follow best practices (such as list cleaning and avoiding high bounce rates), you should be fine.
Q: I already have a Mailbluster account. Can I still buy the Appsumo package?

Tier 2 costs $80 more than Tier 1 and provides 170,000 more emails. At $0.40 / 1000 emails, that is $68, which is $12 less than Tier 1.
Tier 3 costs $240 more and provides 470,000 more emails. At $0.40 / 1000 emails, that is $188, which is $52 less than Tier 1.
Are there any reasons to choose Tier 2 or 3? Tier 1 seems more economical.
Hi - You made a very smart calculation. On our tire,
59/30000 —> 1.96$ per thousand email
139/200000 —> .69$ per thousand
299/500000 —> .59$ per thousand
So, you are paying less per email as you go up.
But if you want to go on a more economic route, starting with tire 1 is a viable option, as you can always purchase extra credits.
