Dear Marketo team,
We have installed marketo in our company since 6 months, but we have a big problem with the e-mails’s deliverability , the opening rate has dropped by 40% in comparison to mailchimp, but especially the emails go to spam, even the in-house sample testing,
we think there is a problem with the setting, would you help us?
There's a lot of discussion around deliverability here on the community: https://nation.marketo.com/search.jspa?q=email%20deliverability
Could be a shared IP issue or possibly emailing more people than Mailchimp was. Remember, Mailchimp automatically blocks inactive emails, bounces, etc. In Marketo, you must setup workflows to handle that.
Hi Meriem Merimeche
I have experienced this problem in my previous place of work when a new instance was installed but the Marketo support team told us that we should expect a high bounce rate initially and that it was normal. To counter this, we staggered our email launches during the first month. Example - If we had a total of 100,000 emails to send we were advised to launch only 20,000 per day over 5 days to reduce the email bounce. This helped us. Maybe you can try this with your instance.
Hope this information helps.
