Do you send cold email campaigns without considering the limits set by your email provider? Then, you risk getting your account blocked.

This article will show the limitations and restrictions for some popular providers: Gmail, Office365, Yahoo!,, AOL Mail, etc. It will also cover their respective sending limits per day or other intervals (e.g: hourly).

Why is it important to know your email sending limits?

Woodpecker email management tool

Woodpecker is a great email management tool that allows you to create and send emails from your mailbox, but it’s worth keeping in mind the limitations of your provider.

While Woodpecker has limits for how many emails can be sent based on what plan you have chosen, there are also service-based restrictions; so make sure those don’t hinder any efforts.

As an email sender, you should always be aware of your limits.

Sending too many emails in a short time can cause all future messages to bounce back as spam or be blocked by the recipient’s inbox—making it impossible for them to receive any other message from that account until 24 hours have passed.

By setting up “delivery times” and limiting how often you send out each campaign, sending high-quality content with personalization is ensured.

The email sending limits you face are not simply for the first message but also all follow-up emails in your campaign.

If that is something you want to avoid, keep track of how many marketing messages will be queued up each day or week.

What are the sending limits of various email hosts?

Note: We update our blog posts frequently, and as such, email limits may change. Therefore, ensure you verify the limits from each email provider’s official page for the latest information.

Free Gmail sending limit

Free Gmail sending limit

Gmail’s email sending limit is 100 messages a day via SMTP, 500 emails per browser. If you want to send more than that, use an address on another domain with Google Workspace (formerly G Suite).

You can get blocked for up to 24 hours if there are too many incoming or outgoing Gmail emails sent in a period and the account will be unavailable until it becomes active again.

This allows you to reach out to vast numbers and gives you control over sending settings.

Plus, your mail recipients will take your message seriously if they receive email from a business domain rather than a free Gmail account.

So when sending emails for outreach purposes, make sure the address looks safe and legit to avoid suspicion.

Google Workspace sending limit

Google Workspace sending limit

Google Workspace (formerly G Suite) has an email sending limit of 2000 messages per day and 500 on trial. If you exceed the limits, your account will be blocked for up to 24 hours before being able to send again.

So be sure that your emails have good deliverability, or they may block you from using Google Workspaces’ service even if it’s free.

If one considers the importance of preventing spam from entering their inbox, it makes sense that reducing these instances should be a priority.

If Google blocks you due to your messages potentially being considered as such in Gmail or Outlook 365, for instance, then you will find yourself with more limited options when trying to get through other email accounts like Office365.

One way to avoid this problem and prevent reaching 2000 daily limits on an account is increasing them sooner rather than later so as not ever better exceed any totals before upgrading would make much sense too!

Office365 sending limit

Office365 sending limit

Office 365 has a limit of 10,000 email recipients per day. There is no hourly limit, but one minute will only allow 30 messages at once, so beware if you’re using automation and the possible risk it may take on your account with sending too many emails in an hour or two.

Woodpecker is the email provider that will help you send unlimited messages per minute without breaching Office 365’s sending limit.

Unlike other providers, which may get your emails blocked due to poor deliverability rates and low inbox ratio, Woodpecker guarantees a 100% delivery rate of every message sent with their service – no more than six minutes between each sent mails. sending limit sending limit

The email sending limit is 300 emails maximum for verified accounts with a good reputation.

Verified means your account has been confirmed to be owned by you and that it hasn’t already accrued any bad habits such as spamming or phishing attempts.

In addition, a good reputation indicates how often you use the service, whether it’s less than 30 days old (which can have lower limits), no complaints against the account, etc.

GoDaddy (Workspace email accounts) sending limit

GoDaddy (Workspace email accounts)

GoDaddy (Workspace email accounts) allows you to send up to 250 emails.

Still, if your daily sending limit is reached early in the day after a few campaigns with follow-ups are sent out, then we recommend scheduling those messages for various days of the week.

If not, use more than one Workspace account or message to don’t overlap and get blocked from future sending by GoDaddy.

Also, note that you can increase your daily sending limit to 500 at an extra cost.

GoDaddy’s email marketing limits are always a tough decision. You never know how much is too much until you’ve hit the limit and have to pay for overages!

Luckily, we don’t need to worry that Woodpecker’s per minute restriction at six emails/minute will keep us safe from exceeding this amount of messages sent in an hour while still delivering our message effectively and efficiently.

Rackspace sending limits

Rackspace sending limits

If you are a company or individual sending emails, be mindful of the quantity and quality.

RackSpace pays close attention to how many complaints they receive for email senders that exceed 10K recipients per day.

Their current limit is at 10 000 recipients per day with no word on an hourly sender limit yet available; however, there is much more concern about the overall message content than any number of messages sent in one hour!

If your communications have been classified as spam by anti-spam filters, it’s not uncommon for your account to get blocked after just reaching 800+ subscribers within minutes from hitting ‘send.’

BlueHost sending limit

BlueHost sending limit

BlueHost’s daily sending limit is not explicitly stated, but they allow for a maximum of 150 emails per hour, with 70 messages sent every half-hour.

If you exceed this rate and experience an email bounce, your account will be disabled until it gets reviewed (usually within 24 hours).

You can get back on track as soon as the problem is resolved!

DreamHost sending limit

DreamHost sending limit

DreamHost allows you to send emails at a rate of 100 per hour, but for this privilege not to be revoked, each message sent must contain no more than five recipients.

In addition, if you are sending five different messages with the same content and only one sender address/name on them, you may have up to 25 sends within 15 minutes.

If using an announcement list, make sure there are never more than 500 email addresses included not to cause any issues or delays.

Yahoo! Mail Plus sending limit

Yahoo! Mail Plus sending limit

Yahoo! Mail Plus is a free email service that offers more than 20GB of storage, spam protection, and features like custom domain forwarding.

But, that’s not all: Yahoo! Mail Plus users can send 500 emails per day, with each recipient limited to 100 recipients.

And because there are no hourly limits on sending mail in the app, it might be your best choice if you’re looking for an unlimited plan – or at least one without any restrictions whatsoever.

Yandex.mail sending limit

Yandex.mail sending limit

Yandex mail is a Russian email service that has recently imposed an inbox limit on sending emails per day.

They say it will help keep their servers running efficiently and smoothly without crashing the engine due to high traffic volumes.

The new rule states you can send 500 messages in one 24-hour period as long as each message only goes out once with multiple recipients (each recipient counts).

Host Gator sending limit

Host Gator sending limit

Sending limits are set in place to ensure nobody sends spam emails.

In terms of quantity, it is better not to send more than 500 emails per hour and 12,000 a day for each domain/subdomain you have registered with Host Gator’s service.

Take note of spikes in your mailbox activity

The key to successful outreach is striking a balance between sending frequent messages and making sure they’re not too often.

If you set periods for longer emails, the message will be sent less frequently on your end while remaining fresh in their minds as it’s been a while since they last heard from you!

Create shorter blocks of time when possible so that there are no spikes in activity or red flags with any email providers who may deem this suspicious behavior.

Research the “golden hours” for your specific prospect group.

For example, if you send to CEOs of large corporations around 2 pm their time zone (noon Eastern), that would be a golden hour – best not sent on Mondays!

But don’t just rely on one-hour segments; give yourself at least two so as not to get blocked out by an automatic mass email program.

However, there are no mandatory golden hours for sending emails.

Instead, you need to identify the optimal time of day and week to achieve your desired response rate among different prospects, so don’t blindly follow what professionals say when developing a successful campaign strategy.


You’re never alone when you send an email, so make sure to consider your recipients and their inboxes.

When sending out emails, the sender must always be aware of the content they are posting and how many people will receive it due to deliverability rates for outgoing messages.

It’s essential to know your limits and not send too many emails. Too many emails can lead to a decrease in open rates, click-through rate, and unsubscribe rate.
