We use Sendy (using Amazon SES) to send email newsletters for some our our clients. Recently, recipients have been complaining that newsletters are landing in their spam.

Does anyone have any experience with deliverability, comparing Amazon SES to something like Mailchimp? Are the deliverability rates of Mailchimp really that much better?

I mentioned briefly in an earlier comment on our experience using SES vs Mailchimp/Mandrill.

Our emails sent through SES, often ended up in people's spam folder despite doing the requisite verifications (SPF, DKIM).

We switched to Mandrill and noticed significant improvements. We don't send alot of emails, but for transactional emails, it's important those are delivered.

Sending emails without images, in plain text, also does improve delivery especially to corporate emails.

We were exploring dedicated IPs, but those require warming up, so frankly we don't send many emails.

Love to hear any other advise for improving email delivery.

I don't know how SES works. Some of the other providers lump groups of users together. If you get in a group with spammers, your sending server gets tarnished. You can usually email support and get moved to a different group.

Not sure if SES offers this. The other guys will. That alone could be reason to try it out? Shouldn't be hard to with gateways for 1 blast and see how it performs.

Indeed, I see connection attempts everyday from mail servers on SES, Mailchimp, Sendgrid, etc., that are blacklisted. That mail will never get delivered to my customers, even if it's 100% legitimately non-spam.

Have you opened a dialog with AWS to see what they suggest or can do to remediate the situation?
