Let’s dig in and find out which service is the best.
The common issues in sending email from a website
Sending emails in the normal way
Most hosting/servers are installed a utility called
sendmail for sending emails from the website to their audiences. Despite its advantage, using
sendmail has a big drawback is that your emails are going to the Spam or Junk folder. You know what it means, don’t you? Your audiences, even your customers, may not read that emails because of missing, of course.
If your website is based on WordPress and uses no plugin for sending email, you will meet the above issue because of using
This problem of
sendmail is raised depending a lot on your server IP and your server/domain set up. For example, your email will be labeled as Spam if your IP is in the blacklist, even not in both blacklist and whitelist also. Domains without valid SPF and DKIM records will meet the same situation. It’s quite complicated to fix.
Besides that, the hosting services also have rules which may affect your sending emails via host or verser. This is the list of sending email limits of hosting providers made by MailPoet. According to this list, not that you always can send plenty of emails at the same time, so you need a solution to remedy this.
Using Gmail SMTP to send emails
Another common way of sending emails from websites is using Gmail SMTP. There are many ways to connect WordPress sites with Gmail such as WP Mail SMTP and Easy WP SMTP, but Gmail SMTP is usually recommended because it’s compatible with the latest Gmail API, use OAuth 2.0, and obviously is secured.
There is a disadvantage that Gmail allows the maximum number of sending emails is 500 per day and 20 per hour. It may be a lot in most need, but not enough for the newsletter and some other cases.
In additional, Gmail SMTP always use the private avatar and email address of the Gmail account which you use for SMTP. It is ok if you are sending email personally, but not ok if you are a company. In this case, most of us are companies, so it’s really a problem with the company brand.
Use transactional email services
To solve all the above problems of sending emails, using transactional email services is the best solution. So, what is the transactional email service? Let’s find it out step-by-step.
What is the transactional email?
Transactional email is sending email automatically from the website to an individual based on their action. It could be:
- an action they took directly
- an action they were the target of or,
- perhaps even inaction on their part
For instance, whenever users buy any Meta Box’s extensions, they will receive an automatic email of notification that they bought something as well as information of their order. That is sent from our website and also is a kind of transactional email.
Another example, there is an area for comments under each post in our blog. If you subscribe a post, you will receive a notification email whenever someone leaves a comment on that. That email also is a transactional email.
Other samples of transactional emails:
- email address confirmations
- password resets
- purchase receipts
- “thank you for [some action]”
- account balance updates
- weekly manifests
- support requests
- cart abandonment
- monthly invoices
- app error alerts (developer tested!)
- automated re-engagement (marketer approved!)
