There are a few things you can check:
- Please back your site up, delete Rapid Mailer, download a fresh copy from your member area, installing it either via FTP or the WordPress dashboard. Not only does this ensure you have the latest version, 1.7.8, this also ensures that you don’t have a bad installation. You won’t lose data by doing this.
- Once this is done, please go to https://imsuccesscenter.com/customercare/index.php?/News/NewsItem/View/7/trouble-shooting and read the post dated Jan. 29, titled “Trouble Shooting” which provides a step-by-step procedure to check for plugin conflicts.
- Please ask your host to have your memory levels set as here:
#Change upload limits
file_uploads = On
post_max_size = 64M
upload_max_filesize = 64M
memory_limit = 256M
#Change upload limits end
Most important part is memory_limit = 256M, they can set it to higher to resolve your issue.
In the case of the upload max file size, this ensures that we can upload things like the Profit Builder Theme with no issue.
- The max execution time simply means that any operations that a plugin or theme is doing will not time out. Memory simply refers to the amount of data that can be processed. Your host can make these changes, typically through cPanel, using a file called php.ini.
- Please ensure you’re using Server Cron and not WP Cron as here: https://imsuccesscenter.com/customercare/index.php?/Knowledgebase/Article/View/96/24/rapid-mailer—email-scheduling-and-setting-up-cron-job
- Confirm that account is in production mode and not in Sandbox mode
- At least one verified email, which you have to use in the from field when configuring Rapid Mailer
- You have verified your domain name with AES.
- You don’t have any leading or trailing white spaces in the SMTP Host
- If using SMTP, you must have DKIM signing set to “on” in Rapid Mailer > Configuration. Additionally, be very careful when inserting the keys>
- Should try these ports [25, 465 & 587] alternately with the TLS & SSL options
- For both Amazon SMTP as well as API Domain and email must be verified as well as SPF and DKIM set up and enabled in a host.
We generally recommend using the SendGrid API option as the free account has similar features to Amazon and it is also far easier to set up, only requiring your account username and password.
For Amazon specifically, please check the following:
As mentioned, while Amazon is an option, I usually recommend and use SendGrid, as it is far easier to set up as mentioned previously and has the same free account options as Amazon.
