Why do my emails go out so slowly?

Why do my emails getting out so slowly? There are many factors that you need to consider when you are sending high volume emails and below are a few general factors:

i) Email size

The size of the e-mail varies on the amount of data and slows the delivery of email if your size of e-mail is large. For instance, the content of your e-mail attachments or graphics like photos. We may suggest that you use connections to web server records.

ii) Invalid email addresses

If there are many bounce backs e-mails because subscribers are rejecting invalid e-mails, which is not double opt-in email addresses, then the e-mail queue will be created and eventually slow down the delivery speed.

iii) Anti-virus

The use of an anti-virus program can occasionally affect the email delivery speed, as each message takes a few seconds before it is sent out.

iv) Transmission speed

It will also affect your email sending experience if your Internet connection speed is slow.

How To Fix?

There a number of ways to fix the problem.

For Shared Hosting User

If you are on a Shared Hosting account, the first option – and simplest – is to delete some of the messages in the folder. The other option is to contact our support team and see if they are eligible to move to a new, more efficient backend storage solution.

For VPS or Dedicated hosting package

If you are on a VPS or Dedicated hosting package, you can consider the options above or opt to upgrade your storage disks to SSDs. This allows your server to handle the larger amount of mail in the folders.

For account created before June 1, 2011

For an account created before June 1, 2011, there are a couple of ways to fix this. The first is to delete some of the emails out of the folder in order to free up space.

Another solution is to change the backend mail storage engine you are using. Accounts created before June 1, 2011, use a different, less efficient backend mail storage engine called MBOX. MBOX’s inefficiency causes high storage folders to hinder the rest of the engine. 

If you want to drastically increase speed, you may want to consider migrating your entire account to one of our currently offered packages. Our current packages use a backend storage system that is even more efficient than Maildir. However, this backend storage option is not compatible with accounts created before June 1, 2011.

Lastly, you can fix the problem by reducing the size of your email. You would need to reduce any large attachments or images in your email. Text only takes up a few KB per sentence, so unless you’re sending an email with thousands of words, you can likely ignore your text. If you can’t reduce your attachment, consider storing it on a shareable platform, such as Google Docs or DropBox, and sharing a link to it in the email.
