Thanks for the feedback.
We agree on all except point 6. I am not sure that many people share one e-mail address, and by definition, the e-mail has only. Perhaps we may solve this with a custom field, and value Mr/Mrs, if no name is set?
I agree with the cases you provide as well. I hope that we will get into shape with the Newsletters module, so that we can think of such scenarios :).
I must say that both feature requests make sense. Actually, we are planning to have those, especially the one with the send interval - it's a must have. AS for the SMTPs, we will most probably have list of predefined SMTPs (like the Google one), which are free to use.
..8 out of 9 is not bad either :)
Marketing analytics will be built in as well, together with A/B campaigns.
We have an option for importing subscribers from csv or excel, but do not support exporting yet.
These improvements are pending. We are definitely looking forward to have them.
