Yii2 how to make an email newsletter?

Question

Yii

On Yii2, I need to do an email campaign. There are not many addresses yet, about 100 approximately.
Is it possible to send mail using yii\swiftmailer\Mailer ?
Or is it better to use something else?
And how to make a mailing to several addresses at once - not to send letters in a cycle?

Answer 1

Or is it better to use something else?

mailchimp.com
Generally it is better to send in a cycle. Emails with multiple recipients are more likely to end up in spam. In general, there is a bunch of everything that needs to be configured so that letters do not fall into spam.

Answer 2

If in the future there will be a lot of letters - 1000 or more. Mail servers of hosters can begin to enter "sanctions". There is an option to push letters, for example, into redis or memcached, and from there, using the key, pull out 200-300 letters at a time with a cron and send them. Get a kind of mail queue
