Slack is for daily comms with our team and clients. Every client gets two channels. An internal channel with just our team and external channel with the client.
Someone asked me: Does deliverability matter for double opt-in newsletters?
Short answer: Yes. Deliverability matters for both single & double opt-in lists.
Longer answer: Double opt-in is a great way to keep your list clean & a great step towards ensuring you have a high
quality list. More context: While double opt-in can help your deliverability through higher engagement, just because you leverage double opt-in upfront, doesn’t mean your subscribers will maintain the same level of high engagement over time. Some form of churn is inevitable.
So cleaning your list ongoing + sending to subscribers who are engaged are just as important with double opt-in as with single opt-in. The only potential difference could be the volume of people that churn that double opted in vs. single opted in, could potentially be lower.
