To be honest I found this article to be a bit blog spammy. It’s for developers because they used a startup accelerator analogy? I didn’t see anything particularly differentiated from the equivalent SendGrid&#x2F;Mailgun&#x2F;etc blogs that come up.<p>This is probably the best demo for understanding SPF&#x2F;DKIM&#x2F;DMARC that I’ve come across (I am not affiliated): <a href="https:&#x2F;&#x2F;www.learndmarc.com&#x2F;" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.learndmarc.com&#x2F;</a><p>If you really want to understand DMARC check it out.

Note that this is about the use case &#x27;authenticating whether the given mail server is authorized to send mail for the given domain&#x27;, not the use cases &#x27;authenticating whether the given user of this mailbox actually sent this email&#x27; or &#x27;authenticating whether the given message is spam or not&#x27;, which is probably the reason you clicked on this article :).<p>The former use case is pretty much solved (in that you can safely ignore email from servers&#x2F;domains that don&#x27;t follow best practices), the latter (combining the 2, since they&#x27;re pretty similar, really) is not, even given recent advances in AI (OpenAI cannot tell you if a message is spam, sorry, unless your prompt engineering skills are much better than mine).

I liked the look of this:<p>&gt;BIMI (Brand Indicators for Message Identification) is this kind of access in the inbox. It sets you apart from all the others by showcasing your brand and legitimacy to your users in the inbox by displaying your logo and, in some cases, a verified checkmark.<p>Until I looked at the cost of a Verified Mark Certificate (1-year plan):<p>&gt;$1,499.00 USD [1]<p>Yikes.<p>Small money for big players, but small businesses with valid brands not so much.<p>[1]<a href="https:&#x2F;&#x2F;order.digicert.com&#x2F;step1&#x2F;vmc_basic" rel="nofollow noreferrer">https:&#x2F;&#x2F;order.digicert.com&#x2F;step1&#x2F;vmc_basic</a>

Anyone willing to share opinions on BIMI?<p>I’m wondering if it is worth it for most medium-large organization or if this is specifically worth it if you are doing a lot of commerce and sending e-mails to customers etc.<p>Furthermore, (stating the obvious) DKIM, SPF and DMARC are also implemented by malicious parties and only authenticate that the server was allowed to send using a particular domain name. BIMI seems to require a VMC (Verified Mark Certificate). Is this verified and is it effective in preventing unauthorized parties from BIMI verifying their domains using stolen brand logo’s etc.<p>Also, is Microsoft Outlook (still) not supporting&#x2F;adopting BIMI?

This is new:<p>&gt;BIMI (Brand Indicators for Message Identification) is this kind of access in the inbox. It sets you apart from all the others by showcasing your brand and legitimacy to your users in the inbox by displaying your logo and, in some cases, a verified checkmark.<p>Apparently this can help me promote my brand. Unfortunately I don&#x27;t have a brand so I fear that this would be used to promote the brands of others at my expense.

Can someone tell me what is it that resend provides over their wrapper (AWS) that makes them this famous?

Does Resend use AWS SES under the hood?

I&#x27;m trying to understand why all BIMI-mail shouldn&#x27;t be simply rejected on the SMTP layer ..

Hey Resend team! Love your product!<p>I was wondering when &#x2F; if you&#x27;ll be supporting inbound email parsing &#x2F; webhooks. It&#x27;s the one thing that&#x27;s preventing me from switching over.<p>Love what you&#x27;re doing - keep it up!
