How many emails can I send per day?
It's critical to warm up your email address because it affects your deliverability.
If you don't follow these best practices, you could get flagged for spam, see your sending throttled, or worse, your domain could get blocked! Check out these guides for best practices you'll need to follow to ensure you end up in the inbox and not the spam folder:

Campaigns have a prospect limit of 5000 prospects, but you can have unlimited Campaigns. Check out this guide for more info: How many prospects can I have in a campaign?
Other limits imposted by your mail provider or email type might apply so check out these limits below:
Limits for Google sending emails:
As of this writing, information on limits can be found here for Gmail accounts and here for G Suite accounts.
Gmail accounts have a sending limit of 500 emails/day.
GSuite accounts have a sending limit of 2000 emails/day.
Google may choose to throttle your sending far below your daily sending limit for any reason which will result in your emails being stopped (see yellow Important note below).
Reasons for throttling your sending could include:
- Sending too many emails at once or too fast (blasting)
- Sending too many emails in a day relative to the age of your email or previous activity
- Other reasons up to Google's discrection.
If we detect that you've reached a Google quota limit we will pause sending for a period of time and then automatically resume later.
However, do not rely on this detection to protect yourself from going over your quota because:
- We usually only get this notice after you've already exceeded your quota
- Sometimes we're not able to make that detection fast enough to stop emails that are already queued up.
Your best bet is to use Mailshake's sending calendar settings to limit how we schedule your messages. Make sure to warm up your email before sending at high volumes. See this guide: Sending Cadence and Copywriting Best Practices for Deliverability - this guide includes a suggested warm-up sending cadence
Keep in mind, if you're sending via an alias, your Google limits apply but so also might any limits that the service that runs your alias email domain has.
Limits for Microsoft sending emails:
Mailshake limits sending via Microsoft accounts to 1000 email/day.
Limits for SMTP sending emails:
When sending via SMTP, you'll need to refer to your email provider's best practices for how many emails you can send per day. Mailshake limits sending via SMTP to 1000 emails/day.
Your mail provider retains the right to throttle your account for any reason, after which you will receive notices that you've hit your quota. We understand this can be very frustrating Our advice is to refer to the above tips on avoiding being flagged as a spammer. The good news at least is that Mailshake detects when a quota was hit and we automatically pause sending for a period of time before resuming so you don't experience a high number of bounces.
If you have questions about why you hit a quota lower than your normal sending limit, you'll want to reach out to your mail provider directly as Mailshake doesn't control these quotas.
