Question 1

What is TenantCore?

Accepted Answer

TenantCore is an outbound email infrastructure platform for domains, mailboxes, DNS, sending tools, alerts, and reports.

Question 2

Is TenantCore a sending tool?

Accepted Answer

No. Your campaigns stay in the sending tool you already use. TenantCore manages the infrastructure behind the mailboxes.

Question 3

What do I need to get started?

Accepted Answer

A Microsoft 365 tenant and the domains you want to use for outbound. TenantCore guides you through the rest.

Question 4

How does TenantCore scale across more environments?

Accepted Answer

Paid plans start with 3 tenant slots, and you can add more for $5/month each. Every additional slot gives you another Microsoft 365 environment to grow into, so your overall domain and mailbox capacity expands with you.

Question 5

Does TenantCore buy domains for me?

Accepted Answer

No. Add domains you already own. TenantCore can help configure the DNS they need.

Question 6

Can TenantCore set up DNS automatically?

Accepted Answer

Yes. Plus and Complete include automatic DNS for supported providers. Base includes guided manual setup.

Question 7

Can I use any domain provider?

Accepted Answer

Yes. TenantCore works with domains from any provider through guided manual DNS. Porkbun, Cloudflare, and eligible Namecheap accounts also support automatic DNS setup.

Question 8

How many cold email inboxes can I run with TenantCore?

Accepted Answer

TenantCore calls them mailboxes, but they are the Microsoft 365 inboxes you connect to your sending tools. Each connected environment supports 12 domains and 3 mailboxes per domain (36 per environment). Add more environments as you grow, so there is no TenantCore-wide mailbox or inbox ceiling.

Question 9

Can I control daily sending limits?

Accepted Answer

Yes. Set each mailbox anywhere from 1 to 25 sends per day so the sending policy stays consistent as you scale.

Question 10

Can I still use Outlook?

Accepted Answer

Yes. You can keep Outlook access while using the same mailboxes with your sending tools.

Question 11

Can TenantCore help with mailbox credentials and MFA?

Accepted Answer

Yes. TenantCore keeps managed credentials and MFA access with the mailbox workflow.

Question 12

Which sending tools can I use with TenantCore?

Accepted Answer

TenantCore mailboxes can be used with any sending tool that supports Microsoft 365 mailbox authentication. Instantly, PlusVibe, Smartlead, and ManyReach have direct TenantCore integrations, but they are not the only sending tools you can use.

Question 13

Do I have to use a direct TenantCore integration?

Accepted Answer

No. Direct integrations make setup faster, but they are not a requirement. If your sending tool supports Microsoft OAuth, you can connect the TenantCore mailboxes you want to use.

Question 14

What does TenantCore monitor?

Accepted Answer

TenantCore tracks infrastructure status, sending-location changes, alerts, and sending-reputation signals.

Question 15

What happens when infrastructure is damaged or something stops working?

Accepted Answer

TenantCore keeps infrastructure status, alerts, activity history, and reporting together so you can see what changed, what it affects, and where to start recovery instead of rebuilding the timeline from separate tools.

Question 16

Can I show a client what happened in their sending infrastructure?

Accepted Answer

Yes. Reports bring sending results, infrastructure status, activity history, and tenant, domain, and mailbox views together so you can answer client questions without rebuilding the story manually.

Question 17

Does TenantCore monitor inbox reputation or inbox placement?

Accepted Answer

TenantCore monitors sending-reputation signals, infrastructure status, sending-location changes, and alerts. It does not claim to prove inbox placement; delivery means the destination mail system accepted the message.

Question 18

What can I see in Reports?

Accepted Answer

See sending results, infrastructure status, activity history, and reporting across tenants, domains, and mailboxes.

Question 19

Can I export reports?

Accepted Answer

Plus adds CSV export. Complete adds PDF, scheduled reports, and portfolio reporting.

Question 20

What can I build during the trial?

Accepted Answer

The 14-day Plus trial gives you 1 tenant slot with the Plus feature set, supporting 12 domains and the normal TenantCore mailbox structure within that environment.

Question 21

What is the difference between Base, Plus, and Complete?

Accepted Answer

Base covers core management. Plus adds automation and sending-tool integrations. Complete adds advanced reporting and API access.

Question 22

Which plan includes API access?

Accepted Answer

Complete includes TenantCore API access.
