We offer two types of mailboxes — SMTP and Google Workspace, as well as a combo of both.
Advantages of SMTP:
Advantages of Google Workspace mailboxes:
Can I delete mailboxes?
Yes.
You purchase a license for a specific number of mailboxes rather than specific accounts. If you delete and recreate them, you don't need to pay extra. However, please note that new mailboxes require a warm-up period.
How do I change the names of mailboxes?

Advantages of SMTP:
- Designed specifically for outbound
- Lower cost (starting from $1.9)
- Fully proprietary infrastructure, including servers and IPs
- Your campaigns are sent from different IPs, and we automatically replace them with new ones if they stop working
- We automatically replace links and images in your emails with safe alternatives using Global Customer Domain Tracking
- Burned-out mailboxes are automatically disconnected from campaigns for 14 days to recover
- We run inbox placement tests every 3 days and display up-to-date health scores for each mailbox.
Advantages of Google Workspace mailboxes:
- More stable deliverability, according to various estimates
- Automatic connection to your sequencer
- Ability to add a profile picture
- Each domain is hosted on a separate, fully isolated Google Workspace account.

Are domains included in the plans?
Yes, but only for quarterly SMTP plans. For monthly plans, they must be purchased separately, or you can connect your existing domains.
How much do domains cost?
The domain registration fee is $12 per year. This price is fixed and does not change based on the number of domains.
You can purchase domains on the pricing page or in your personal account on the Packages & Add-ons page.
Which TLD's are available for domain registration?
We use the following TLDs for domain registration: .com, .net, .org, .one, .co, .email, .ink, .digital, .company, .pro, .services, .space, .co.uk, .de.
Can I connect my own domains? Yes. To do this, send a list of your domains to our support team via the website chat or at help@realmaildoso.com
You can also connect external domains yourself via the API. For this, consult the API documentation and watch our Loom video.
Do I retain ownership of domains purchased through Maildoso?
While you are using our service, domains are registered with us, enabling us to facilitate processes such as creating emails, IP rotation, and more.
You can request that the domains be returned at any time, and we will transfer them back to you at no charge at the end of your subscription.
How many mailboxes can I create per domain?
My domain is burned or blacklisted. What should I do?
In some cases, you may request a free domain replacement. Learn more in this article.

How many emails can I send from one mailbox?
Can I send emails to free email hosting services (@gmail.com, @yahoo.com, etc.)?
Our infrastructure is optimized for B2B outreach. As a result, campaigns targeting personal email providers may experience reduced inbox placement when sent from standard Maildoso mailboxes.
To address this, we have recently started offering authentic Google Workspace mailboxes that are better suited for sending to personal email providers. These mailboxes are designed to improve inbox placement when targeting contacts on Gmail, Outlook, Hotmail, and similar platforms.
You can learn more about these Google Workspace mailboxes on the GW product page.
- Google Workspace: 15 cold emails / 25 warm-up emails per day (with slow ramp-up).
- SMTP: 15 cold emails / 80 warm-up emails per day, no slow ramp-up (clarify if your sequencer allows for this volume of warm-up emails).
