What the experts say3Expert opinions
Expert from Spam Resource shares that seedlist providers can give you a general idea of delivery, but aren't the be-all and end-all of deliverability testing. Some providers she mentions are 250ok (now Validity), Return Path (now Validity), Litmus, Email on Acid, and GlockApps.
Expert from Email Geeks shares that all inbox placement test tools are as accurate as each other (middling accurate for places like gmail) and to pick whichever one is in your price range and has the display you like.
Expert from Word to the Wise responds that no seedlist is 100% perfect. Most seedlists are fairly accurate, you just need to take them with a grain of salt.
