I have approximately 230,000 email addresses that I’m looking to submit a new one-off email campaign to (already written).
The following issues are of particular importance to me:
• The emails show as having been sent from my email account, not a third-party system
• It is simple for recipients to reply to my email and/or opt out of future campaigns
• Any invalid email addresses are removed from the list pre-sending and any inactive email addresses are removed from the list before it is returned to me post-campaign
• Any duplicate email addresses in the lists are eradicated before beginning the campaign
• Firewalls and spam-boxes are avoided – I don’t just want the emails sent, but also read.
