DO YOU KNOW YOUR EMAIL SERVICE PROVIDER’S SENDING LIMIT?
Finding the right email service software is crucial in determining what works best for your company. That said, just because one email marketing solution is popular doesn’t mean it’s the right fit for you.
SMTP e-mail services are a great way to send your message directly to the people who matter most to your company and at the right time of delivery without any hassle.
When dealing with bulk email notifications or big marketing campaigns, many things can go wrong – personalization problems, obsolete lists, numerous follow-ups, and so on. These can all be dealt with, with the help of the right service platforms. But when it comes to the sending part of your campaign, you don’t need a tool, you need to know the limitations of sending email. .
Not all outgoing SMTP mail servers were created equal, and how much your email can send each hour or each day will be determined by the particular outgoing SMTP mail server that you use to relay your messages. These limits are based on a daily, hourly, or per-minute basis. The limits for a Microsoft 365 email service may vary depending on the email limits allocated to each organization.
Why is knowing the email sending limits of your provider important?
Otherwise, your email campaign may go undelivered and your account may be blocked. After the recipient rate limit is reached, messages can’t be sent from the mailbox until the number of recipients that were sent messages in the past 24 hours drops below the limit.
Each ISP, web hosting, and email provider establishes its own email sending policy which outlines specifically how many emails you can send through their outgoing SMTP mail server per connection, per hour or per day
Why do ISPs, web hosting, and free email providers have email sending limits?
Hourly and daily email sending limits are not nefarious. They exist simply to control the level of email traffic being processed, to ensure that the mail server will be available to support all of its users whenever they need to send an email, and to prevent spam from being sent through their system. Not unlike speed limits on highways, byways, and motorways around the world, email sending limits exists to establish control to keep everything moving along smoothly.
To give you the most accurate insight into various limitations from email service providers, the under-listed points should be put into consideration with the following issues: performance, attachment size limits, recipients/messages per hour limits, and daily email limits.
- Email attachment size limit. If your email campaign involves attachments, make sure they fit the attachment size limits of your provider. Every ESP differs in this parameter, for example, the Gmail attachment size limit is 50MB while iCloud email attachment limit is 20 MB.
- Recipients/messages per hour limit. Every provider sets its own limits, the breaking of which can lead to a temporary ban. Choose your provider’s plan according to the size of your campaign.
- Daily email limit. The amount of emails that can be sent in a day without getting banned, also varies from one provider to another.
- Performance. Email systems are not designed to transfer large volumes of data. They deal with SMTP, which is quite an outdated protocol. Most of the systems are not able to process multiple data sources at once. In addition, mail transfer agents often scan incoming data for viruses and other potential risks, which also takes resources and affects system performance.
