For context I run a SaaS targetting small&amp;#x2F;medium businesses, who usually have in-house email servers with extremely restrictive spam filters. The IP was on a blacklist, so some of my customers just couldn&amp;#x27;t use my service. I contacted SendGrid and their only solution was to upgrade from a $20&amp;#x2F;mo plan to a $80&amp;#x2F;mo plan with a dedicated IP - they wouldn&amp;#x27;t even move me to another IP in the pool.&lt;p&gt;Given this, and my volumes of mail were increasing (once you go over 100k emails&amp;#x2F;mo SendGrid&amp;#x27;s pricing goes up a lot), I setup my own mail server using Cuttlefish [0]. I set it up on an OVH instance that I pay £2.50&amp;#x2F;mo for. I contacted them to enquire about spam policies before opening an account, and they said they take it very seriously and monitor outgoing SMTP for spam.&lt;p&gt;The IP address I ended up with was still on one blacklist, but the process to remove it was pretty easy (fill out a form, and explain the situation) and took about 1 day. I set this up around 6 months ago and have had no problems with deliverability since then, I&amp;#x27;m now up to sending around 300k emails per month.&lt;p&gt;[0] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;basho&amp;#x2F;cuttlefish&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;basho&amp;#x2F;cuttlefish&lt;/a&gt;</text><parent_chain><item><author>jwr</author><text>I tried using Sendgrid and was surprised to find out that unless you buy an expensive plan, then:&lt;p&gt;* You get IPs from a shared pool, and the reputation is nowhere near guaranteed.

This way, transactional email (and sure, I guess marketing from your company) would be able to get through and the email given out wouldn&amp;#x27;t be able to be used if sold or stolen, as the receiving mail server would reject it because of a bad signature (bad sender, and coupled with DKIM and SPF, a malicious user wouldn&amp;#x27;t be able&amp;#x2F;allowed to spoof the sender&amp;#x27;s email).</text><parent_chain><item><author>jwr</author><text>I tried using Sendgrid and was surprised to find out that unless you buy an expensive plan, then:&lt;p&gt;* You get IPs from a shared pool, and the reputation is nowhere near guaranteed.
