Estimated value

What this plugin might earn a year, and what it might sell for. Modeled from public signals; we don't see anyone's books.

medium confidence

Est. annual revenue

≈$12K range $2.5K–$60K

Est. acquisition value

≈$35K range $5K–$240K

Modeled from public signals only; the real figure depends on pricing and conversion we cannot see. The range spans more than 10x because wp.org publishes install counts as broad bands, and conversion and price compound on top. Read the midpoint as an order of magnitude, not a valuation.

How we estimate this

Assumptions

  • Free → paid conversion. 0.5%–2% of active installs pay for the pro tier. Typical for freemium WordPress plugins; the real rate varies a lot by product.
  • Annual price per customer. $49–$149 a year, typical for Email & Marketing plugins rather than this plugin's own pricing.
  • Acquisition multiple. 2x–4x annual revenue, the going range for small WordPress-plugin businesses, the typical range for a steady plugin.
  • Install base. 10K–20K active installs, from our install estimate (wp.org only publishes the floor).

Revenue is installs × conversion × price; value is revenue × a typical acquisition multiple. Every factor is an assumption band, so the output is a wide range on purpose. If you're buying or selling, treat this as a starting point for due diligence.

    I’ve been through many mailing plugins, often changing each year. WP Offload SES hasn’t given me any reason to look elsewhere.

    I love everything these guys do. They have a way of creating plugins that’s all their own. They’re deceptively simple to install, and very workmanlike, solid and reliable in what they do. Also, they’re very easy to troubleshoot. I know that if I ever have a problem, I know it won’t be the plugin and the chances are that I screwed up somewhere. So if I have a choice, I will choose a Delicious Brains plugin every time. You should too.

    Hi, I am using WP SES plugin in our website using AWS secret and key id. I am recently receiving below message from AWS. Hello, Amazon Simple Email Service (SES) had extended support for Signature Version 3 to February 28th, 2021. To continue to use Amazon SES, you must migrate to Signature Version 4 which offers enhanced security for authentication and authorization of Amazon SES customers. We have identified that, between 2021-03-22 and 2021-03-29, your AWS account 553361156523 used Signature Version 3 to call Amazon SES APIs in the us-east-1 Region. Your Signature Version 3 requests were identified to be originating from: - IAM Users: arn:aws:iam::------:user/sendynew - IPs: 18.212.163.144 - User Agents: SimpleEmailService/php Your Signature Version 3 requests were identified to be using the following SES actions: - APIs: SendEmail Example Request ID using Signature Version 3: d2eeef38-18d9-49ee-bc04-516d42680246 You can identify API requests that use Signature Version 3 by looking at the request headers. Requests that use the Signature Version 3 resemble the following example (note the "AWS3"): X-Amzn-Authorization: AWS3-HTTPS AWSAccessKeyId=AKIAIOSFODNN7EXAMPLE,Algorithm=HMACSHA256,Signature=lBP67vCvGl ... To move to Signature Version 4: - If you are self-signing your requests, refer to our documentation for Authenticating requests to the Amazon SES API [1] and creating a canonical request for Signature Version 4 [2]. - If you are not self-signing your requests, simply update your SDK/CLI to the latest version. The Amazon SES team will update the request information weekly and will stop notifications once we identify that Signature Version 3 is no longer being used from your account. Also, in the SES setting, below message is appearing Sending emails through Amazon SES is currently OFF But mails are coming. Please suggest what should I do. Thanks, Suman Kumar This topic was modified 5 years, 3 months ago by suman4468.

    Emails say they are successfully being sent but I am not receiving any emails. I set up AWS SES in Production mode and included the correct access keys, so everything should be working, but I’m getting nothing. They are not in junk either. I am experienced with AWS and have never had this problem. This plugin just straight up didn’t work for me. Disappointing.

    BEST PLUGIN TO SEND EMAILS THROUGH AMAZON SES Just lately, we are getting false email alerts saying that cron is not working, which is wrong, because emails are sent and received. Thank you to fix this.
