AppRanks verdict
Generated from live marketplace data — refreshed daily
Surbma | SMTP is a newly-listed WordPress app with a limited review volume. It is listed in the Email category on WordPress Plugin Directory, which AppRanks treats as the canonical taxonomy node for ranking and competitor comparison. no published reviews yet means feature claims are unverified by the wider merchant base. Without a published review base, the only fit-signal available is the developer's own documentation plus the marketplace's listing-quality audit (linked below). Paid-only pricing means evaluating fit on the marketplace listing or via the developer's documentation before installing. AppRanks tracks rating, review count, pricing tier, and category position daily — the figures on this page reflect the most recent scrape from the canonical WordPress Plugin Directory listing.
Pros
- +Published by Surbma — established developer track record
Cons

How Surbma | SMTP works
Show full descriptionShow less
This plugin is created especially for Multisite Networks. You can define all variables in the wp-config.php file and it will be valid for all sites in a Multisite. So this is not for a site-by-site configuration plugin. You can install it on a single WordPress install also and it will work perfectly. But if you install it in a Multisite Network, you can only network activate it!
This plugin is working with all SMTP servers and services, like Mailgun, SendGrid, Mandrill, Amazon SES and others.
Required variables:
SURBMA_SMTP_HOST – External SMTP server.
SURBMA_SMTP_USER – User for the SMTP account.
SURBMA_SMTP_PASSWORD – Password for the SMTP account.
Optional variables:
SURBMA_SMTP_PORT – Port number for the SMTP server.
SURBMA_SMTP_SECURE – Choose SSL or TLS, if necessary for your SMTP server.
SURBMA_SMTP_FROM – From email address for all outgoing emails.
SURBMA_SMTP_FROMNAME – From name for all outgoing emails.
Example configuration:
define('SURBMA_SMTP_HOST','smtp.mailgun.org'); define('SURBMA_SMTP_USER','[email protected]'); define('SURBMA_SMTP_PASSWORD','bb2b********4133');
You can put these lines everywhere before the line, that says: “That’s It. Pencils down”
